» Java programs are divided into two main
categories, applets and applications
» An application is an ordinary Java program
» An applet is a kind of Java program that can
be run across the Internet
Applets: Introduction

SSBN Degree College, ATP M Vishnuvardhan
» Applets are mainly used convert a static web
page to dynamic page
» Web is created with the help of Hypertext
markup language (HTML).
» Web site is collection of webpages of a
particular organization.
» A browser is a software which is used to browse
the internet ie., used to view web pages
Applets: Introduction

SSBN Degree College, ATP M Vishnuvardhan
» Applets do not use main() method
» Applets needs html code to run
» Applets are run by Java enabled
web browser.
» Applets are by default GUI Apps.
Applets vs. Applications

SSBN Degree College, ATP M Vishnuvardhan
» To deal with applets in java a special class is
defined in java.applet package called as
Applet.
» Applet class contains five special methods
init() :- used for initialization of applet
start() :- used to start an applet
paint() :- used to paint the contents of the
applet on the window
stop() :- used to stop an applet
destroy() :- used to destroy an applet
»Applet methods are automatically called one
after another once they are loaded into web
browser
Applet Class

SSBN Degree College, ATP M Vishnuvardhan
In order to create an applet the following steps
are to be followed
»Create a class by extending applet class
»Override any one of the applet class method
»Compile the program to obtain the class file
»Create a html document and embed the applet
»Run the applet along with the html page in
java enabled web browser
Creation of Applets

SSBN Degree College, ATP M Vishnuvardhan
// Sample Applet program
import java.awt.*;
import java.applet.*;
public class DemoApp extends Applet
{
public void paint(Graphics g)
{
g.drawString(“Java applets”, 50,50);
}
}
Note:- After compiling the program embed the applet in a
html file and open in java enabled web browser.

SSBN Degree College, ATP M Vishnuvardhan
An Applet is embedded in a html file using
<applet> tag. Applet tag contains three main
attributes
Code :- specifies the class name of applet
Height :- specifies the height of the applet
Width :- specifies the width of the applet
Alignment :- specifies the alignment of applet
Hspace :- specifies the horizontal and
Vspace :- vertical space around the applet
EG:-
<applet code=“Demo” width=“300” height=“300”>
</applet>

It is possible to pass data from a html page to
applet program. This can be done with the
help of <PARAM> tag in html
<APPLET .. . .. . .>
<PARAM name=“ ..” value=”…”/>
</APPLET>
Here the name corresponds the name of the
parameter and value associates the value of
the parameter
Passing parameters to Applet

SSBN Degree College, ATP M Vishnuvardhan
The parameters from the <PARAM> tag can be
read in the applet program with the help of
following method
String getParameter(String name):
returns the value associated with the
specified parameter.

It describes using validation controls on both the client-side using JavaScript and server-side using C# to check fields for errors like empty values, values outside a specified range, or values that do not match a regular expression. The key validation controls covered are RequiredFieldValidator, RangeValidator, RegularExpressionValidator, CompareValidator, and CustomValidator. It emphasizes best practices of using both client-side and server-side validation for security and usability.

Basic Concepts of OOPs (Object Oriented Programming in Java)Michelle Anne Meralpis

This document provides an overview of basic object-oriented programming (OOP) concepts including objects, classes, inheritance, polymorphism, encapsulation, and data abstraction. It defines objects as entities with both data (characteristics) and behavior (operations). Classes are blueprints that are used to create objects. Inheritance allows objects to inherit properties from parent classes. Polymorphism allows code to take different forms. Encapsulation wraps data and functions into classes, hiding information. Data abstraction focuses on important descriptions without details.

Jdbc architecture and driver types pptkamal kotecha

JDBC provides a standard interface for connecting to and working with databases in Java applications. There are four main types of JDBC drivers: Type 1 drivers use ODBC to connect to databases but are only compatible with Windows. Type 2 drivers use native database client libraries but require the libraries to be installed. Type 3 drivers use a middleware layer to support multiple database types without native libraries. Type 4 drivers connect directly to databases using a pure Java implementation, providing cross-platform compatibility without additional layers.

Sessions and cookieswww.netgains.org

Cookies and sessions allow servers to store and retrieve information about users across multiple page requests that would otherwise be stateless. Cookies store data in the user's browser, while sessions store data on the server. Cookies have limits on size and number, while sessions can store larger objects but expire when the browser closes. PHP provides functions like setcookie() and $_SESSION to easily manage cookies and sessions for maintaining state in web applications.

This document discusses servlets, which are Java programs that extend the capabilities of web servers to enable dynamic web content. Servlets run on the server-side and generate HTML responses to HTTP requests from clients. The document covers the basics of servlets, how they interface with web servers, their lifecycle including initialization and destruction, advantages over previous technologies like CGI, and implementation details.

Enterprise java unit-2_chapter-3sandeep54552

The document discusses session management in servlets. It defines a session as a way to track a client's activity across multiple requests by saving a unique ID associated with the client. When the client first makes a request, the web container generates a session ID and returns it to the client. The client then sends the session ID with subsequent requests so the web container can associate requests with the correct session. Common techniques for managing sessions include cookies, hidden form fields, URL rewriting, and HTTP sessions. HTTP sessions allow data to be stored on the server side and accessed throughout the application.

An applet is a small Java program that runs in a web browser. It allows for interactive graphics and animation to be embedded in HTML pages. Applets differ from standalone Java applications in that they have no main method and run within the context of a web page. The lifecycle of an applet involves initialization, starting, stopping, and destruction as the user interacts with the web page. Parameters can be passed to applets using the <param> tag in HTML. The applet code uses methods like init(), paint(), start(), and stop() to control its execution and display output.

Java basics notesGomathi Gomu

Java programs are portable across operating systems due to three features: 1) the standardized Java language, 2) the portable class library, and 3) translating source code to portable byte code rather than platform-specific machine code. The Java language is secure through interpreter-level checks and browser-level restrictions for applets. It is also robust through features like garbage collection and bounds checking that prevent crashes. Java programs come in two flavors - standalone applications or applets for web programming. Applets have additional restrictions and predefined lifecycle methods that are automatically invoked by web browsers.

Applet Architecture - Introducing Java Appletsamitksaha

- Applets are small Java applications that run within web browsers. They are embedded in HTML pages and can interact with the user. - Applets follow an event-driven model where the AWT notifies the applet of user interactions. The applet then takes action and returns control to the AWT. - The applet lifecycle includes init(), start(), stop(), and destroy() methods that are called at different points as the applet loads and runs within the browser.

Python Datatypes.pptxM Vishnuvardhan Reddy

There are several built-in data types in Python including numeric, text, sequence, mapping, and boolean types. Numeric types store numbers and include int, float, and complex types. Text is represented by strings which can be single, double, or multi-line. Common sequence types are lists, tuples, and ranges which store ordered collections of values. Mappings store key-value pairs using dictionaries. Boolean type represents True and False values.

Html formsM Vishnuvardhan Reddy

An HTML form is used to collect user input and consists of form fields, labels, and buttons. Forms can be processed using client-side programming, which performs tasks within the browser, or server-side programming, which runs on the server. Common client-side languages include JavaScript and CSS, while common server-side languages include PHP, ASP.NET, and Python. The <form> tag creates an HTML form and contains input elements like text fields, checkboxes, and submit buttons. Forms are submitted using either the GET or POST method, with POST being preferable for sensitive data since it does not display submitted values in the URL.

Cascading Style SheetsM Vishnuvardhan Reddy

CSS (Cascading Style Sheets) is used to style and lay out web pages. CSS describes how HTML elements should be displayed on screen, paper, or other media. CSS saves time by allowing consistent styling across multiple web pages from a single external CSS file. CSS rules contain selectors that point to HTML elements and declaration blocks with properties and values that define the styling. Common CSS properties include color, font-size, padding, borders, background, positioning and more. CSS rules can be applied via internal, inline and external stylesheets and the different styles cascade together following certain precedence rules.

Java ThreadsM Vishnuvardhan Reddy

Java StreamsM Vishnuvardhan Reddy

Streams are used to transfer data between a program and source/destination. They transfer data independently of the source/destination. Streams are classified as input or output streams depending on the direction of data transfer, and as byte or character streams depending on how the data is carried. Common stream classes in Java include FileInputStream, FileOutputStream, FileReader, and FileWriter for reading from and writing to files. Exceptions like FileNotFoundException may occur if a file cannot be opened.

Scanner classM Vishnuvardhan Reddy

The document discusses different ways to read input in Java programs, including using System.in.read() to read a single character, stream classes which are flexible but complex, and the Scanner class which was added in JDK 1.5 and is easy to use. It provides details on using the Scanner class, noting that an object is created from a source such as the keyboard, file, or network, and methods are used to read the appropriate data type from the source. Common Scanner methods are listed that can read primitive types and strings.

PolymorphismM Vishnuvardhan Reddy

Polymorphism in Java can occur at compile-time via method overloading or at run-time via method overriding. Method overloading involves declaring multiple methods with the same name but different parameters within a class. The compiler determines which overloaded method to call based on the number and type of parameters passed. Method overriding occurs when a subclass has a method with the same name and parameters as a method in the parent class. Run-time polymorphism is demonstrated when an object of the subclass is treated as the parent class type and the method call is resolved based on the object's actual type at runtime.

Java introM Vishnuvardhan Reddy

Exception handling M Vishnuvardhan Reddy

The document discusses exception handling in Java. It describes different types of errors like compile-time errors and run-time errors. It explains checked and unchecked exceptions in Java. Checked exceptions must be handled, while unchecked exceptions may or may not be handled. Finally, it covers how to create user-defined exceptions in Java by extending the Exception class and throwing exceptions using the throw keyword.

Control structuresM Vishnuvardhan Reddy

This document discusses control structures in Java programming. It describes two types of control structures: branching structures and looping structures. Branching structures like if-else and switch statements allow modifying the flow of a program based on certain conditions. Looping structures like while, for, and do-while loops allow repeating blocks of code. Specific looping structures like nested loops, labeled loops, and enhanced for loops are also covered.

ConstructorsM Vishnuvardhan Reddy

The document discusses constructors in Java. It defines a constructor as a special method used to initialize an object's properties. It provides the rules for creating a constructor, such as the constructor must have the same name as the class and no return type. The document compares constructors and methods, and lists the properties of constructors. It also discusses the two types of constructors: the default constructor provided by the compiler if none is defined, and the parameterized constructor that takes parameters.

Classes&objectsM Vishnuvardhan Reddy

Shell sortM Vishnuvardhan Reddy

Shell sort is an improvement on insertion sort that aims to overcome insertion sort's inefficiency for average cases. It works by comparing elements separated by a distance to form multiple sublists, then applying insertion sort on each sublist to move elements towards their correct positions in a way that allows elements to take bigger steps. This reduces the number of comparisons needed compared to regular insertion sort.

Slack like a pro: strategies for 10x engineering teamsNacho Cougil

You know Slack, right? It's that tool that some of us have known for the amount of "noise" it generates per second (and that many of us mute as soon as we install it 😅). But, do you really know it? Do you know how to use it to get the most out of it? Are you sure 🤔? Are you tired of the amount of messages you have to reply to? Are you worried about the hundred conversations you have open? Or are you unaware of changes in projects relevant to your team? Would you like to automate tasks but don't know how to do so? In this session, I'll try to share how using Slack can help you to be more productive, not only for you but for your colleagues and how that can help you to be much more efficient... and live more relaxed 😉.

Challenges in Migrating Imperative Deep Learning Programs to Graph Execution:...Raffi Khatchadourian

Efficiency is essential to support responsiveness w.r.t. ever-growing datasets, especially for Deep Learning (DL) systems. DL frameworks have traditionally embraced deferred execution-style DL code that supports symbolic, graph-based Deep Neural Network (DNN) computation. While scalable, such development tends to produce DL code that is error-prone, non-intuitive, and difficult to debug. Consequently, more natural, less error-prone imperative DL frameworks encouraging eager execution have emerged at the expense of run-time performance. While hybrid approaches aim for the "best of both worlds," the challenges in applying them in the real world are largely unknown. We conduct a data-driven analysis of challenges---and resultant bugs---involved in writing reliable yet performant imperative DL code by studying 250 open-source projects, consisting of 19.7 MLOC, along with 470 and 446 manually examined code patches and bug reports, respectively. The results indicate that hybridization: (i) is prone to API misuse, (ii) can result in performance degradation---the opposite of its intention, and (iii) has limited application due to execution mode incompatibility. We put forth several recommendations, best practices, and anti-patterns for effectively hybridizing imperative DL code, potentially benefiting DL practitioners, API designers, tool developers, and educators.

DevOpsDays SLC - Platform Engineers are Product Managers.pptxJustin Reock

Platform Engineers are Product Managers: 10x Your Developer Experience Discover how adopting this mindset can transform your platform engineering efforts into a high-impact, developer-centric initiative that empowers your teams and drives organizational success. Platform engineering has emerged as a critical function that serves as the backbone for engineering teams, providing the tools and capabilities necessary to accelerate delivery. But to truly maximize their impact, platform engineers should embrace a product management mindset. When thinking like product managers, platform engineers better understand their internal customers' needs, prioritize features, and deliver a seamless developer experience that can 10x an engineering team’s productivity. In this session, Justin Reock, Deputy CTO at DX (getdx.com), will demonstrate that platform engineers are, in fact, product managers for their internal developer customers. By treating the platform as an internally delivered product, and holding it to the same standard and rollout as any product, teams significantly accelerate the successful adoption of developer experience and platform engineering initiatives.

Could Virtual Threads cast away the usage of Kotlin Coroutines - DevoxxUK2025João Esperancinha

This is an updated version of the original presentation I did at the LJC in 2024 at the Couchbase offices. This version, tailored for DevoxxUK 2025, explores all of what the original one did, with some extras. How do Virtual Threads can potentially affect the development of resilient services? If you are implementing services in the JVM, odds are that you are using the Spring Framework. As the development of possibilities for the JVM continues, Spring is constantly evolving with it. This presentation was created to spark that discussion and makes us reflect about out available options so that we can do our best to make the best decisions going forward. As an extra, this presentation talks about connecting to databases with JPA or JDBC, what exactly plays in when working with Java Virtual Threads and where they are still limited, what happens with reactive services when using WebFlux alone or in combination with Java Virtual Threads and finally a quick run through Thread Pinning and why it might be irrelevant for the JDK24.

Enterprise Integration Is Dead! Long Live AI-Driven Integration with Apache C...Markus Eisele

We keep hearing that “integration” is old news, with modern architectures and platforms promising frictionless connectivity. So, is enterprise integration really dead? Not exactly! In this session, we’ll talk about how AI-infused applications and tool-calling agents are redefining the concept of integration, especially when combined with the power of Apache Camel. We will discuss the the role of enterprise integration in an era where Large Language Models (LLMs) and agent-driven automation can interpret business needs, handle routing, and invoke Camel endpoints with minimal developer intervention. You will see how these AI-enabled systems help weave business data, applications, and services together giving us flexibility and freeing us from hardcoding boilerplate of integration flows. You’ll walk away with: An updated perspective on the future of “integration” in a world driven by AI, LLMs, and intelligent agents. Real-world examples of how tool-calling functionality can transform Camel routes into dynamic, adaptive workflows. Code examples how to merge AI capabilities with Apache Camel to deliver flexible, event-driven architectures at scale. Roadmap strategies for integrating LLM-powered agents into your enterprise, orchestrating services that previously demanded complex, rigid solutions. Join us to see why rumours of integration’s relevancy have been greatly exaggerated—and see first hand how Camel, powered by AI, is quietly reinventing how we connect the enterprise.

Crazy Incentives and How They Kill Security. How Do You Turn the Wheel?Christian Folini

Everybody is driven by incentives. Good incentives persuade us to do the right thing and patch our servers. Bad incentives make us eat unhealthy food and follow stupid security practices. There is a huge resource problem in IT, especially in the IT security industry. Therefore, you would expect people to pay attention to the existing incentives and the ones they create with their budget allocation, their awareness training, their security reports, etc. But reality paints a different picture: Bad incentives all around! We see insane security practices eating valuable time and online training annoying corporate users. But it's even worse. I've come across incentives that lure companies into creating bad products, and I've seen companies create products that incentivize their customers to waste their time. It takes people like you and me to say "NO" and stand up for real security!

1. SSBN Degree College, ATP M Vishnuvardhan Java Applets -M Vishnuvardhan, Dept. of Computer Science, SSBN Degree College, ATP

2. SSBN Degree College, ATP M Vishnuvardhan » Java programs are divided into two main categories, applets and applications » An application is an ordinary Java program » An applet is a kind of Java program that can be run across the Internet Applets: Introduction

3. SSBN Degree College, ATP M Vishnuvardhan » Applets are mainly used convert a static web page to dynamic page » Web is created with the help of Hypertext markup language (HTML). » Web site is collection of webpages of a particular organization. » A browser is a software which is used to browse the internet ie., used to view web pages Applets: Introduction

4. SSBN Degree College, ATP M Vishnuvardhan » Applets do not use main() method » Applets needs html code to run » Applets are run by Java enabled web browser. » Applets are by default GUI Apps. Applets vs. Applications

5. SSBN Degree College, ATP M Vishnuvardhan » To deal with applets in java a special class is defined in java.applet package called as Applet. » Applet class contains five special methods init() :- used for initialization of applet start() :- used to start an applet paint() :- used to paint the contents of the applet on the window stop() :- used to stop an applet destroy() :- used to destroy an applet »Applet methods are automatically called one after another once they are loaded into web browser Applet Class

6. SSBN Degree College, ATP M Vishnuvardhan In order to create an applet the following steps are to be followed »Create a class by extending applet class »Override any one of the applet class method »Compile the program to obtain the class file »Create a html document and embed the applet »Run the applet along with the html page in java enabled web browser Creation of Applets

7. SSBN Degree College, ATP M Vishnuvardhan // Sample Applet program import java.awt.*; import java.applet.*; public class DemoApp extends Applet { public void paint(Graphics g) { g.drawString(“Java applets”, 50,50); } } Note:- After compiling the program embed the applet in a html file and open in java enabled web browser. Creation of Applets

8. SSBN Degree College, ATP M Vishnuvardhan Html is a language used to design a web page Basic structure of html file is <html> <! ------Comment Section ---- > <head> <title> title of the page </title> </head> <body> Body of the web page </body> </html> HTML

9. SSBN Degree College, ATP M Vishnuvardhan Commonly used html tags <b> … </b> <i> … </i> <u> … </u> <h1> .. </h1> to <h7> … </h7> <applet> …. </applet> HTML

10. SSBN Degree College, ATP M Vishnuvardhan An Applet is embedded in a html file using <applet> tag. Applet tag contains three main attributes Code :- specifies the class name of applet Height :- specifies the height of the applet Width :- specifies the width of the applet Alignment :- specifies the alignment of applet Hspace :- specifies the horizontal and Vspace :- vertical space around the applet EG:- <applet code=“Demo” width=“300” height=“300”> </applet> Embedding an applet in html file

11. SSBN Degree College, ATP M Vishnuvardhan Applet life cycle contains four necessary states 1. Born or Initialization state 2. Running State 3. Idle state 4. Dead state In this four states applet class five methods are executed on after another. Applet Life Cycle

12. SSBN Degree College, ATP M Vishnuvardhan Applet Life Cycle Born Running Idle Dead start() stop() destroy() start() paint() Loading of applet Exit of browser

13. SSBN Degree College, ATP M Vishnuvardhan It is possible to pass data from a html page to applet program. This can be done with the help of <PARAM> tag in html <APPLET .. . .. . .> <PARAM name=“ ..” value=”…”/> </APPLET> Here the name corresponds the name of the parameter and value associates the value of the parameter Passing parameters to Applet

14. SSBN Degree College, ATP M Vishnuvardhan The parameters from the <PARAM> tag can be read in the applet program with the help of following method String getParameter(String name): returns the value associated with the specified parameter. Passing parameters to Applet
