Method Detail

nonNegativeAbs

public static int nonNegativeAbs(int a)

Returns the closest non-negative int value to the absolute value of a. Works the same way as Math.abs(int) for all values except Integer.MIN_VALUE, for which Math.abs(int) returns negative value but this method returns Integer.MAX_VALUE.

Use this method instead of the standard one if it's important to get non-negative result and Integer.MIN_VALUE may be passed as an argument (e.g. if the argument is a result of Object.hashCode() or Random.nextInt() call).
