For the command line arguments 0 to 127 the program returns true. If I pass 128 or above the program returns false. Can some body explain me what would be the reason...

class TestClass
{

public static void main(String[] args)
{
Integer i = Integer.parseInt(args[0]);
Integer j = i;
i--;
i++;
System.out.println((i==j));

}
}

If the value p being boxed is true, false, a byte, a char in the range \u0000 to \u007f, or an int or short number between -128 and 127, then let r1 and r2 be the results of any two boxing conversions of p. It is always the case that r1 == r2.

This forum is for posting your results on a Cert exam. I am going to move this to the more appropriate SCJP Forum.

Thanks
