Java Inheritance example

public class Inheritance {

public static void main(String[] args) {
// TODO Auto-generated method stub
Second obj = new Second();
First obj1 = new First();
obj.setage(10);
obj1.setage(20);
System.out.println("The value is " +obj.i);
System.out.println("The value is " +obj1.i);
}

}

public class First {

int i;

String S;

void setage(int i){

this.i=i;

}

void setname (String S){

this.S=S;

}

int getage(){

return i;

}

String getname(){

return S;

}

}

class Second extends First{

int j;

void setrollno(int i){

j=i;

}

}

output:-

Test one
