Recipe: `return` is unnecessary as the last statement in a `void` method

[yeikel]

Before :

private void login(String name){

        if ("peter".equals(name)){
            System.out.println("Hi admin");
            return;
        }else {
            System.out.println("Access denied");
            return;
        }
    return;
    }

After :

private void login(String name){

        if ("peter".equals(name)){
            System.out.println("Hi admin");
        }else {
            System.out.println("Access denied");
        }
    }

This would be a good application of DFA capabilities as well... We're basically looking for whether the last expression prior to the return is "downwards exposed"?
