[lang] IllegalArgumentException factory methods

[Gary Gregory]

Hi All:

Similar to Objects.requireNonNull() but for IAEs:

/**
* Factory methods for {@link IllegalArgumentException}.
*/
class IllegalArgumentExceptions {

private static <T> T requireNonNull(T obj, String message, Object...
args) {
if (obj == null) {
throw new IllegalArgumentException(String.format(message,
args));
}
return obj;
}

public static <T> T requireNonNull(T obj) {
return requireNonNull(obj, "Argument");
}

public static <T> T requireNonNull(T obj, String argumentName) {
return requireNonNull(obj, "%s MUST not be null", argumentName);
}

}

Suitable for [lang] I would think.

Thoughts?

I would add to Validate with different names, or adopt an entirely new
approach to constructing exceptions, like that demonstrated in [1].
