The Java Collection Framework provides interfaces and implementations for commonly used data structures like lists, sets, maps and queues. Some key interfaces include Collection, Set, List, Map and SortedSet. Common implementations are ArrayList, LinkedList, HashSet, TreeSet, HashMap and TreeMap. The framework also includes iterators for traversing collections and algorithms for sorting. Generic types were introduced in Java 5 for type-safe collections.
GUI Programming in JAVA (Using Netbeans) - A ReviewFernando Torres
The powerpoint provides the user with a review of various concepts of GUI programming in JAVA. It covers various concepts like :
1. What is IDE ?
2. Various Methods and Properties of Components
3. Variable declaration
4. Data types
Etc
We are covering following topics:
If...Else...Elseif Statements: if statement executes some code if one condition is true.
Switch Statement: Switch Statement tests a variable against a series of values.
For Loop: For loop executes a block of code a specified number of times.
While Loop: While loop executes a block of code as long as the specified condition is true.
Do…While Loop: Do...While loop will always execute the block of code once, it will then check the condition, and repeat the loop while the specified condition is true.
Micronaut: A new way to build microservicesLuram Archanjo
Over the years microservices architecture has been widely adopted in conjunction with Spring Boot. But recently, we are witnessing the rise of microframeworks such as Micronaut, which has innovated the way we build microservices by providing low memory consumption, fast startup, non-blocking, and other important features that I will demonstrate and conceptualize in this talk.
Data Structure in C Programming LanguageArkadeep Dey
This document contains program code in C language for various operations on arrays, linked lists, and recursion. It includes programs for 1) creating and manipulating 1D and 2D arrays, 2) basic singly linked list operations like creation, traversal, counting nodes, insertion, deletion and reversal, 3) recursion based programs for factorial, GCD, Fibonacci series, tower of Hanoi and 4) menu driven programs to perform linked list operations like insertion and deletion at different positions. The programs demonstrate basic data structures concepts in C.
Clean Architecture helps you build applications that are Independent of Frameworks, UI, Database or any external agency. This talk will be an introduction to Clean Architecture principles and system design in Python. We will choose a sample application and walk through a simple use case of creating clean code.
What you will gain from this talk:
* Grow your application with confidence
* Build applications to be independent of infrastructure like Web Frameworks, Database etc.
* Avoid mixing of business logic across different layers of your application
* Test close to 100% of your core business logic
* Keep your tests fast and independent of infrastructure (DB, Web Layer etc.)

This document discusses various print functions in PHP including print(), echo(), printf(), sprintf(), var_dump(), and print_r(). The print() function displays output and returns true but cannot print multiple statements. The echo() function is slightly faster than print() and can display multiple statements. The printf() and sprintf() functions output formatted strings, with sprintf() writing output to a variable. The var_dump() function displays a variable's type and value. The print_r() function displays human-readable output for arrays and objects.
O documento descreve as principais funcionalidades do sistema gerenciador de banco de dados Oracle, incluindo sua história, organização física e lógica, objetos lógicos como tabelas e índices, linguagem PL/SQL, gerenciamento de usuários e privilégios.
This document discusses different types of joins in SQL for combining data from multiple tables, including:
1. Equijoins to retrieve data based on matching column values.
2. Outer joins to also return rows with non-matching column values.
3. Self-joins to join a table to itself based on related columns.
The document discusses various methods for sharing data between Angular components, including:
1) Parent to child components using @Input to pass data via templates.
2) Child to parent using @ViewChild and AfterViewInit lifecycle hook to access child component properties.
3) Child to parent using @Output and event emitters to emit data on user events like button clicks.
4) Between unrelated components using a shared service with RxJs Subjects to share stream of data between all components accessing the service.
(Big) Data Serialization with Avro and ProtobufGuido Schmutz
The document describes data serialization formats Avro and Protobuf. It provides an overview of their schema definition approaches, data types, code generation capabilities, and usage from Java. Key differences noted are Protobuf uses field numbers while Avro relies on schemas and uses variable length encoding. The document also shows examples of defining schemas in IDL format and generating/serializing data from Java code.
O documento fornece uma introdução sobre HTML, destacando que é uma linguagem de marcação usada para exibir conteúdo na web. Explica que a HTML passou por muitas alterações desde sua criação até a versão atual (HTML5) e que o foco será apenas na linguagem HTML e o que pode ser feito com ela.
Schematics allow developers to define rules that transform a file system tree representation. They provide a workflow tool for scaffolding new components and services as well as updating existing code. The Angular CLI uses schematics under the hood to provide its functionality. Developers can build their own schematics to customize workflows by defining rules that apply transformations to a tree representation of files.
This is a basic tutorial on Spring core.

The document discusses several models for representing hierarchical or tree-like data structures in relational databases, including adjacency list, closure table, path enumeration, nested set, and various extensions of the David Chandler model. It provides examples of creating tables and querying data for each model, and notes some advantages and limitations of each approach.
This document provides an overview of ASP.NET Core, including:
1. ASP.NET Core is a cross-platform framework for building modern cloud-based web applications using .NET that can run on Windows, Linux, and Mac OS.
2. It is designed to be modular and include only necessary packages, making it faster and lighter weight than previous ASP.NET frameworks. It also supports dependency injection and inversion of control out of the box.
3. The project structure for an ASP.NET Core application includes folders for wwwroot (for static files), Properties (for settings), and Dependencies (for NuGet and client-side packages). Configuration is done through the Program.cs and Startup
Oracle data integrator 12c - getting startedMichael Rainey
Oracle Data Integrator (ODI) is a data integration tool that can extract, load, and transform heterogeneous data sources. It is flexible and uses a flow-based mapping approach. The presentation provided an overview of ODI and guidance on installation, configuration, and getting started with the developer quickstart to create models, schemas, and mappings between data stores. Key components like knowledge modules generate integration code, while packages and load plans orchestrate the data integration processes.
ADO.NET is a data access technology that allows applications to connect to and manipulate data from various data sources. It provides a common object model for data access that can be used across different database systems through data providers. The core objects in ADO.NET include the Connection, Command, DataReader, DataAdapter and DataSet. Data can be accessed in ADO.NET using either a connected or disconnected model. The disconnected model uses a DataSet to cache data locally, while the connected model directly executes commands against an open connection.
This document provides information about Dapper and Dapper.SimpleCRUD, two libraries that simplify data access with .NET and SQL Server. It discusses installing the libraries via NuGet, and how they enable executing queries, inserts, updates, deletes and stored procedures with minimal code. Dapper.SimpleCRUD adds additional functionality like model attributes and one-to-many mapping to simplify working with related data. Links are also provided to tutorials and Stack Overflow questions about more advanced Dapper features.
This document discusses authenticating Angular apps with JSON Web Tokens (JWTs). It begins with background on OAuth 2.0 bearer tokens and then explains that JWTs are commonly used as bearer tokens. It describes the three parts of a JWT - the header, payload, and signature. It outlines the JWT authentication token lifecycle, from a user logging in to receive a JWT from the server to sending that JWT on subsequent requests. Finally, it presents an Angular HTTP interceptor design pattern to automatically add the JWT to requests by intercepting HTTP calls and modifying the authorization header.
This document discusses Java's delegation event model for handling events. It describes the key concepts of event sources that generate events, event listeners that handle events, and event classes that represent specific events. It provides details on common event classes like MouseEvents and KeyEvents. It also explains the various event listener interfaces and the basic two-step process of using the delegation event model: 1) implementing the listener interface and 2) registering the listener with the appropriate source.
