Delegate vs Callback in Java

Question

I have some misunderstanding about terms of delegates and callbacks in Java.

class MyDriver {

    public static void main(String[] argv){
        MyObject myOb         


        

Answer 1

What you want to achieve is bidirectional communication between the original caller and a service while avoiding the service to depend on the client. The pattern you use for that goal often depends on the restrictions of your language. You use function pointers, closures or, if you have none of these, callback objects (which might also be seen as closures).

And then there are often lots of different names for the same or a very similar pattern.
