What is inheritance in JAVA programming?

Answer 1

Inheritance in JAVA programming is the process by which one class takes the property of another class.

The new classes, known as derived classes or subclasses, take over the attributes and behavior of the pre-existing classes, which are referred to as base classes or super classes.

It helps the programmer to re-use the class just by modifying minor objects and methods in it.

class person

{

attribute-name,address

}

class Emp extends person

{

attribute-(same as parent class)name,address

own attribute-salary(modification)

}

Answer 2

Object-oriented programming allows classes to inheritcommonly used state and behavior from other classes. In the Java programming language, each class is allowed to have one direct superclass, and each superclass has the potential for an unlimited number of subclasses

The syntax for creating a subclass is simple. At the beginning of your class declaration, use the extends keyword, followed by the name of the class to inherit from

public class A extends B {

.....

}

Now class A inherits all features of class B.

This is Inheritance

There is an another example:

you can create like this

this is a first class

class alpha{

void a1(){

system.out.println("This is class alpha's comment");

}

}

this is a second class

class zero extends alpha{

public static void main(String[]args){

zero z1=new zero();

a1.z1();

}

}

output should be : This is class alpha's comment

the important thing is you must save this file as zero. Java (Second class name)

this is a simple example of Java you can create complicate one thought out this example
