The link mvw posted ( Why can't I define a static method in a Java interface? ) describes the reason for not allowing static methods in interfaces and why overriding static methods iis not a good idea (and thus not allowed).
It would be helpful to know in what situation you want to use the static method. If you just want to call a static method of the class, jut give it another name as andy256 suggested. If you want to call it from an object with a reference to the interface, do you really need the method to be static?
To get around the problem, my suggestion is that if you really want to call a static method with the same signature as the interface method, call a private static method:
class MyClass implememts SomeInterface {
@Override
public int someMethod(int arg1, int arg2) {
return staticMethod(arg1, arg2);
}
private static int staticMethod(int arg1, int arg2) {
// TODO: do some useful stuff...
return arg1 + arg2;
}
}
