Guava Release 11's IntMath | Javalobby
Guava Release 11's IntMath class provides three more "checked" methods that throw an ArithmeticException when the given mathematical operation results in an overflow condition. These methods are for addition, substraction, and multiplication and are respectively called IntMath.checkedAdd(int,int), IntMath.checkedSubtract(int,int), and IntMath.checkedMultiply(int,int). As discussed in conjunction with IntMath.checkedPow(int,int), the advantage of this occurs in situations where it is better to have an exception and know overflow occurred than to blindly operate on an erroneous value due to an overflow condition.
