48. Why Integer.MIN_VALUE == - Integer.MIN_VALUE coderanch.comInteger.MIN_VALUE is indeed -2147483648. If we are to negate that we would get 2147483648. However, int doesn't go past 2147483647.

63. Why does negation of Integer.MIN_VALUE display the same value ? forums.oracle.comMelanie_Green wrote: An Integer has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive). 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. More precisely, we negate a twos-complement number by flipping the bits and then adding 1. Integer.MIN_VALUE is 10000000 00000000 00000000 00000000, so we flip the bits, ... |
