What is the output of the following program? import java.io.*; class sample3 { int a; int b; sample3() { a=0; b=0; } sample3(int b1,int c1) { a=b1; b=c1; } final void print() { System.out.print(a); System.out.print(b); } } class sample31 extends sample3 { int c; sample31() { c=0; } sample31(int c) { this.c=c; super(4,5); } public static void main(String args[]) { sample3 ob1=new sample3(4,5); sample31 ob=new sample31(); System.out.print(ob.a); System.out.print(ob.b); System.out.print(ob.c); sample31 ob2=new sample31(5); System.out.print(ob2.a); System.out.print(ob2.b); System.out.print(ob2.c); }
