In 2's complement arithmetic, the smallest negative number of a given size is one larger in magnitude than the largest positive number of the same size. For example, a long runs from -9223372036854775808 to 9223372036854775807. If you take the absolute value of Long.MIN_VALUE, there is no correct answer representable as a Long.
