Conditional templates in Java?

Question

In C# I can do this:

public class QuadTree<T> where T : IHasRect

Is there a way to do something similar in Java?

Answer 1

If where T : IHasRect means that T is a type that must implement the IHasRect interface, the Java equivalent is

public class QuadTree<T extends HasRect>
