What is the output of the given program? public class Test128 { public static void

main(String[] args) { A a = new A2(); B b = new B2(); System.out.println(a.a + b.b); } }

class A { int a = 1; } class A2 extends A { int a = 2; } class B { public int b = 1; } class B2

extends B { public int b = 2; }

Output of following code:- int a = 5; int b = a; a*=2; b+=1; System.out.println(a); System.out.println(b);

Output of the given program? import java.util.Properties; public class Test72 { public static void main(String[] args) { Properties p = new Properties(); p.put('grade', 'master'); Properties p2 = new Properties(p); System.out.println(p2.get('grade') + ' : ' + p2.getProperty('grade')); } }

Output of the following code: int a = 5; while(a > 3){ System.out.print(a--); }
