Why does negation of Integer.MIN_VALUE display the same value ?

Question

Hi Guys,
This is my code :
package declarations;
public class dec32 {
     public static void main(String[] args) {
          int a = Integer.MIN_VALUE;
          int b = -a;
          System.out.println( a+ " "+b);
O/P : -2147483648 -2147483648Now,my question is why does b which is actually negation of the value of a,again print -2147483648 ?
Thank you for your consideration.

Since negative -2,147,483,648 equals 2,147,483,648 which is one value over the maximum, it ticks over to -2,147,483,648 again.
Thank you for your consideration.Your welcome.
