Equivalent of C++ variadic templates in Java

Question

I wish to write a generic type safe observer in Java. In C++, I can easily do it by using variadic template from c++11, like following:

class Observer<typename... T>
{
    void update(T... args);
};

Now, in java, the best I could do is:

class Observer<T>
    {
        void update(T args);
    };

Now, update can not take multiple arguments of different types like in C++. Could someone suggest a solution to this problem?

Thanks in advance.

Answer 1

If all the arguments extend/implement T you can say:

class Observer<T>{
        void update(List<? extends T> args){}
}
