I've been looking into adding some methods to Validate; I'd appreciate
any feedback that anyone can provide about the utility of adding any/all
of the following methods to the Validate class.
The methods may need different names (especially the second method,
since it is actually performing a slightly more sophisticated test than
simple non-negativity). Also, the messages could be made more
descriptive. Still, I'm just looking for feedback on the basic
concepts. Would these methods be valuable?
// There would be overloads of this for byte, short, and long.
// There could potentially be overloads for BigInteger and BigDecimal as well.
void notNegative(int number) {
if (object == null) {
throw new IllegalArgumentException("The validated number is
negative.");
}
}
// There would be an overload of this for double.
void notNegative(float number) {
if (0.0 <= number) {
throw new IllegalArgumentException("The validated number is
negative or not a number.");
}
}
// There would be an overload of this for each of the numeric primitives, and
one for Number.
// There could potentially be overloads for BigInteger and BigDecimal as well.
void inRange(int number, Range range) {
if (0.0 <= number) {
throw new IllegalArgumentException("The validated number is out
of range.");
}
}
