Class is a raw type. References to generic type Class should be parameterized

Question

I have the following class (from a simple Spring tutorial)

public class CarValidator implements Validator {

    public boolean supports(Class aClass) {
             


        

Answer 1

Since the interface forces you to use the raw type (i.e. doesn't allow you to specify the correct type information) you can't implement it without warnings unless you use @SupressWarnings.

The only real fix is to fix the interface (i.e. make it define boolean supports(Class aClass)).
