Utils is a small Java module designed to provide a number of convenience methods for regular expressions, mathematical operations, operations on strings, etc. It aims at having as few dependencies as possible (especially since there are few modularized libraries are out there).
Some examples:
Maths.isLong("123L");
Maths.compensatedSum(1e100, 1e-100, 1, 2e-18);
Strings.ordinalNumeral(3);
Types.canBeWidened(float.class, 3L);
The artifact can be found at maven central:
