Doubt #2

[AJAY JOSE PAUL]

What happens when you try to compile and run the following class...
public class TestClass{
public static void main(String[] args) throws Exception{
int a = Integer.MIN_VALUE;
int b = -a;
System.out.println( a+ " "+b);
}
}


Output?

Your comments please... with explanations.

What happened when you compiled and ran the code? What do you not understand about the output?

Well... the output did not make sense to me.
The output is -2147483648 -2147483648

Any idea?

Printing Integer.MIN_VALUE will give you -2147483648 and again negating this number will give [phone] (out of the range from Integer.MAX_VALUE i.e. equals to Integer.MAX_VALUE+1).Doing the 2's compliment airithmetic to fit this number in 32 bit scheme ,you will get the answer as -2147483648.
