Puzzle-12 Object or Value

Language – Java | Type – Concept | Last date 05-Apr-2009 12:00 p.m. IST | Points 2

We all know that ‘==’ operator check for Object reference equality. It’s not supposed to compare values. That is why I was bugged when I tried the code below and got the ‘impossible output’. Can you tell me why?

package com.twisters;
class IntegerEquality{

public static void main(String args[]){
Integer first = 100;
Integer second = 100;
if(first == second)
        System.out.println(“This is impossible!!”)
else
        System.out.println(“Everything is as expected out here.”)
}
}

Got an answer? Why don't you leave it here.
