Programming

What output is produced by the following code?  Explain how it works.

public class A {

int a = 1;

int b = 2;

public int getSum(int a, int b) {

    this.a+=a;

    this.b+=b;

    return this.a + this.b;

}

}

public class B extends A {

int a = 3;

int b = 4;

public int getSum(int a, int b) {

    this.b=a;

    super.b=b+b;

    return super.a+this.b;

}

}

public class q2 {

public static void main(String[] args){

A a = new A();

B b = new B();

System.out.println(a.a + \" \"+ b.b);

System.out.println(a.getSum(a.a,b.b));  

System.out.println(a.b + \" \"+ b.b);

System.out.println(b.getSum(a.b,b.b));

System.out.println(a.a+\"\"+a.b + \" \" +b.a+\"\"+b.b);
