function - Best practice for returning multiple values in Java?

Question

Today I've added a extra security check behind my login forms, to slow down brute force attacks. I've got multiple login forms and made a nice easy to call function that does all the checking and then returns the result.

public static ValidateLoginResult validateLogin(HttpServletRequest request, String email, String password) {

The problem is the result is not a single value, the result consists of:

boolean ok
String errorMessage
boolean displayCaptcha

For this I created a new class. This all works fine.

But I often have handy utility functions that return multiple values and start to find it a bit annoying to create a new class for the result every time.

Is there a better way of returning multiple values? Or am I just lazy? :)

No, this kind of structure doesn't exists nativily in Java, but you can look at JavaTuples library that may suit your need and provide a quite elegant solution. Using a Triplet<Boolean, String, Boolean>
