Inheritance in JAVA PPT
Inheritance in JAVA PPTPooja Jaiswal This document discusses inheritance in object-oriented programming. It defines inheritance as establishing a link between classes that allows sharing and accessing properties. There are three types of inheritance: single, multilevel, and hierarchical. Single inheritance involves one parent and one child class, multilevel inheritance adds intermediate classes, and hierarchical inheritance has one parent and multiple child classes. The document provides examples of inheritance code in Java and demonstrates a program using inheritance with interfaces. It notes some limitations of inheritance in Java.

It provides examples of inheritance in Java using keywords like extends, super, this. Interfaces are discussed as a way to achieve multiple inheritance in Java. The document also discusses implementation of inheritance in C# using concepts like calling base class constructors and defining virtual methods.
Java collections concept
Java collections conceptkumar gaurav This document discusses the collection framework in Java. It provides an overview of the need for collections due to limitations of arrays. It then describes the key interfaces in the collection framework - Collection, List, Set, SortedSet, NavigableSet, Queue, Map, SortedMap, and NavigableMap. For each interface, it provides a brief description of its purpose and characteristics. It explains that collections allow storing heterogeneous data types with variable sizes, unlike arrays.
Inheritance ppt
Inheritance pptNivegeetha This document discusses inheritance and method overriding in Java. It defines inheritance as a mechanism where one class inherits features from another superclass. There are different types of inheritance in Java including single, multilevel, hierarchical and multiple inheritance through interfaces. Method overriding allows a subclass to provide its own implementation of a method defined in the superclass without modifying the superclass. The rules for overriding include matching argument lists and not overriding private, static or final methods. Overriding enables dynamic binding at runtime.
Software Testing Fundamentals

Java Lambda Expressions.pptx
Java Lambda Expressions.pptxSameerAhmed593310 Lambda expressions were added in Java 8 as a way to implement functional programming. They allow short, anonymous blocks of code to be passed around as parameters or returned from methods. A lambda expression takes parameters and returns a value without needing a name or class. They provide a concise way to represent method interfaces via expressions and simplify software development by providing implementations for functional interfaces.

Java threads
Java threadsPrabhakaran V M A thread is an independent path of execution within a Java program. The Thread class in Java is used to create threads and control their behavior and execution. There are two main ways to create threads - by extending the Thread class or implementing the Runnable interface. The run() method contains the code for the thread's task and threads can be started using the start() method. Threads have different states like New, Runnable, Running, Waiting etc during their lifecycle.
Java packages
Java packagesBHUVIJAYAVELU Packages in Java are used to organize classes and avoid naming conflicts. A package contains related classes and groups them by functionality. Packages can be stored in JAR files. Fully qualified class names include the package name to uniquely identify classes. There are Java API packages and user-defined packages. The Java API packages contain commonly used classes organized by functionality. Packages are specified using dot notation and control access to classes.
Inner classes in java
Inner classes in javaPhD Research Scholar - Java inner classes are classes declared within other classes or interfaces. They allow grouping of logically related classes and interfaces and can access all members of the outer class, including private ones.
- There are three main advantages of inner classes: they can access private members of the outer class, they make code more readable by grouping related classes, and they require less code.
- The two types of inner classes are non-static (inner) classes and static nested classes. Non-static classes can access outer class members like private variables while static classes cannot access non-static members only static ones.
- Examples demonstrate member inner classes, anonymous inner classes, local inner classes, and static nested classes in Java and how they can

Jdbc architecture and driver types ppt
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.
Inheritance C#
Inheritance C#Raghuveer Guthikonda Inheritance allows one class to inherit properties and behaviors from another base class. There are two main types of inheritance: implementation inheritance, where a derived class takes on all members of the base class; and interface inheritance, where a derived class inherits only function signatures without implementations. Key aspects of inheritance in C# include defining virtual methods that can be overridden, using modifiers like sealed to restrict inheritance, and implementing interfaces that define common behaviors without implementations.
Interface in java
Interface in javaPhD Research Scholar This document discusses interfaces in Java. It defines an interface as a blueprint of a class that defines static constants and abstract methods. Interfaces are used to achieve abstraction and multiple inheritance in Java. They represent an "is-a" relationship. There are three main reasons to use interfaces - for abstraction, to support multiple inheritance functionality, and to achieve loose coupling. The document provides examples of interfaces, such as a Printable interface and implementations in different classes. It also demonstrates multiple inheritance using interfaces and interface inheritance.

Generics in java
Generics in javasuraj pandey Generics in Java allows the creation of generic classes and methods that can work with different data types. A generic class uses type parameters that appear within angle brackets, allowing the class to work uniformly with different types. Generic methods also use type parameters to specify the type of data upon which the method operates. Bounded type parameters allow restricting the types that can be passed to a type parameter.
java interface and packages
java interface and packagesVINOTH R An interface in Java is a blueprint of a class that defines static constants and abstract methods. Interfaces are implemented by classes where they inherit the properties and must define the body of the abstract methods. Key points are:
- Interfaces can only contain abstract methods and static constants, not method bodies.
- Classes implement interfaces to inherit the properties and must define the abstract method bodies.
- An interface can extend other interfaces and a class can implement multiple interfaces.

java_vyshali.pdf
java_vyshali.pdfVyshali6 This document discusses inheritance in object-oriented programming. Inheritance allows classes to inherit features from other classes, called parent or super classes. The class that inherits is the child, derived, or subclass. Java uses the "extends" keyword for a subclass to inherit from a superclass. Inheritance provides benefits like code reusability, increased reliability, and consistent interfaces. The main types of inheritance discussed are single, multilevel, hierarchical, multiple and hybrid inheritance. The advantages of inheritance include minimizing duplicate code, flexibility, and overriding methods, while disadvantages include slower function calls and increased coupling between classes.
Inheritance and Polymorphism
Inheritance and PolymorphismKartikKapgate - Inheritance allows one class to acquire properties and behaviors of another class. A subclass inherits from a superclass.
- Polymorphism allows one action to be performed in different ways. In Java it occurs through method overloading and overriding.
- Method overloading involves multiple methods with the same name but different parameters. Overriding involves a subclass method with same signature as the superclass method. Overriding enables polymorphism at runtime while overloading involves compile-time polymorphism.
Inheritance used in java
Inheritance used in javaTharuniDiddekunta Inheritance allows one class to acquire properties and behaviors of another class. This allows code reusability and runtime polymorphism through method overriding. There are three types of inheritance in Java: single, multilevel, and hierarchical. Multiple inheritance is not supported in Java through classes due to complexity and ambiguity issues that can arise.
Inheritance in OOPs with java
Inheritance in OOPs with javaAAKANKSHA JAIN Inheritance in java introduces the concept of reusability by implementing a mechanism in which one object acquires all the properties and behaviors of the parent object.
Inheritance in Java is a mechanism in which one object acquires all the properties and behaviors of a parent object. It is an important part of OOPs (Object Oriented programming system).
The idea behind inheritance in Java is that you can create new classes that are built upon existing classes. When you inherit from an existing class, you can reuse methods and fields of the parent class. Moreover, you can add new methods and fields in your current class also.
Inheritance represents the IS-A relationship which is also known as a parent-child relationship.
OOPS Characteristics
OOPS Characteristicsbaabtra.com - No. 1 supplier of quality freshers This document discusses the key concepts of object-oriented programming (OOP) including objects, classes, encapsulation, inheritance, polymorphism, and abstraction. It defines objects as instances of classes that have data fields and methods. Classes contain both data and functions and can have private, public, or protected members. Encapsulation binds data and functions into a class. Inheritance allows deriving new classes from existing ones. Polymorphism enables classes to provide different implementations of methods with the same name. Abstraction simplifies complexity by modeling appropriate classes for a problem.
Inheritance
InheritanceMunsif Ullah Inheritance allows reuse of properties and behaviors of an existing class when creating new classes. The existing class is called the base/parent class, while the new class is the derived/child class. The child class inherits all properties and behaviors of the parent class and can define additional properties and behaviors of its own. There are different types of inheritance like single, multilevel, multiple and hierarchical inheritance which define how properties and behaviors are inherited between parent and child classes.
Java OOPS Concept
Java OOPS ConceptRicha Gupta This document discusses the core concepts of object-oriented programming (OOP) in Java, including inheritance, encapsulation, abstraction, and polymorphism. It provides examples of each concept: inheritance allows classes to inherit properties from parent classes; encapsulation involves hiding data and code together within classes; abstraction deals with hiding details and focusing on essentials through abstract classes and interfaces; polymorphism allows classes to take different forms. The document uses examples like vehicles and medical capsules to illustrate how each OOP concept works in Java code.

It provides examples of how encapsulation hides implementation details and inheritance allows classes to inherit properties from superclasses. Polymorphism allows objects to take on multiple forms through inheritance. Abstract classes cannot be instantiated directly but provide a common definition that concrete subclasses implement. Interfaces define behaviors for classes to implement but do not provide implementations.

Inheritance in Java
- 1. Inheritance in Java Tamanna Akter ID: 171-15-8903
- 2. What is Inheritance? Inheritance in java is a mechanism in which one object acquires all the properties and behaviors of parent object. Inheritance represents the IS-A relationship, also known as parent-child relationship.
- 4. Java Supports a special feature called interface. This feature helps to connect a class with more than one classes. For this type of connectivity java uses ‘implements’ keyword. Syntax : interface A{ ……} Interface B { ____} class M { -------} class N implements A,B extends M{ ===== _____------…………} Indirect Mechanism of Inheritance
- 5. Sample Code of Inheritance class Calculation { int z; public void addition(int x, int y) { z = x + y; System.out.println("The sum of the given numbers:"+z); } public void Subtraction(int x, int y) { z = x - y; System.out.println("The difference between the given numbers:"+z); } } public class My_Calculation extends Calculation { public void multiplication(int x, int y) { z = x * y; System.out.println("The product of the given numbers:"+z); } public static void main(String args[]) { int a = 20, b = 10; My_Calculation demo = new My_Calculation(); demo.addition(a, b); demo.Subtraction(a, b); demo.multiplication(a, b); } }
- 6. Advantages of Inheritance ● Reusability -- facility to use public methods of base class without rewriting the same ● Extensibility -- extending the base class logic as per business logic of the derived class ● Data hiding -- base class can decide to keep some data private so that it cannot be altered by the derived class ● Overriding -- With inheritance, we will be able to override the methods of the base class so that meaningful implementation of the base class method can be designed in the derived class.
- 7. Disadvantages of Inheritance • Unsupported- Java not support Multiple inheritance as well as Hybrid inheritance. • Permits only one class- The extends keyword permits to connect a class with only one class. • Undefined- In Interface, properties are only declared and assigned, but never defined. • Re-factor- If a method is deleted in the "super class" or aggregate, then we will have to re-factor in case of using that method.
