Java generics - is it possible to restrict T to be Serializable?

Is it possible to make something like this? I know that implements cannot be in the <>, but I want to restrict the T to be Serializable somehow.

public class Clazz<T implements Serializable> {
    ...
}

Yes, just use extends instead of implements.
