Java generics and interface

Vincent asked me if it was possible to specify that a generic parameter must implements a specific interface. Well that's possible but instead of writing:
T implements MyInterface
you need to do:
T extends MyInterface
Here's the full code listing:

public interface Toto {
    public void execute();
}

public class TotoImpl implements Toto {
    public void execute() {
        System.out.println("execute");
    }
}

public class Foo <T extends Toto> {
    private T t;
    public void setObject(T t) {
        this.t = t;
    }
    public T getObject() {
        return t;
    }
    public void doSomething() {
        t.execute(); 
    }
}

public class Main {
    public static void main(String[] args) {
        Toto toto = new TotoImpl();
        Foo foo = new Foo();
        foo.setObject(toto);
        Toto notCastedToto = foo.getObject();
        foo.doSomething();
    }
}

update: thanks to nico to point that > and lt; wasn't display in the code, making it pointless ;)
