Inheritance: Inheritance allows a class (subclass) to acquire the properties and behavior of another class (superclass). In java, a class can inherit only one class(superclass) at a time but a class can have any number of subclasses. It helps to reuse, customize and enhance the existing code. So it helps to write a code accurately and reduce the development time. Java uses extends keyword to extend a class.
class A{
public void fun1(int x){
System.out.println("int in A");
}
}
class B extends A{
public void fun2(int x,int y){
fun1(6); // prints "int in A"
System.out.println("int in B");
}
}
public class C{
public static void main(String[] args){
B obj= new B();
obj.fun2(2);
}
}
In the above example, class B extends class A and so acquires properties and behavior of class A. So we can call method of A in class B.
