I'm trying to implement an stack using a linked list in Java, But I'm not sure which methods I have to implement(stack is a simple example here), How can I somehow get the methods and then extend my linked list class to implement my own class of stack

I know that somehow I have to use some kind of interface but it would be a great help if someone could guide me here.

    You can have a look at the Stack class from the API to see which methods to implement : docs.oracle.com/javase/7/docs/api/java/util/Stack.html Commented Jan 5, 2014 at 16:46

    Java doesn't have modules! I suggest you don't ever mention the word module if you want to pass a Java interview. Commented Jan 5, 2014 at 16:58

A stack at its simplest just has Push() and Pop(). They map directly to the LinkedList methods push and pop already present!

So in order to implement a stack on top of a linked list you need to do....nothing :)
