What is the output of the following code?

IN JAVA

public class hw1{ public static void main(String[] args) { System.out.println(new A()); System.out.println(new B()); } } public class A { public int i; public A() { i = 1; } public String toString() { return String.format("2 %d", i); } } public class B extends A { public B() { i = 3; } public String toString() { return String.format("4 %d", i); } }
