Hi there.
This is a question related to Math.abs().
Why Math.abs(Integer.MIN_VALUE)and Math.abs(Long.MIN_VALUE)returns -ve value.
Looking forward for your valuable answers??

Hi Jiji,

The negation of Integer.MIN_VALUE (-2147483648) will result in overflow since the range for int is -2147483648 to 2147483647. Same for long.

It is sorta covered in the JavaRanch Style Guide.
