ok, so what can i do to make Queue<String> aQueue = new LinkedList<String>(); work? If I remove the implements linkedList from the queue class will this correct it? I am going to test it in the meanwhile... Ok i just tried it out... it says "incompatible types" ( which is why i put implements.. in in the first place)

cool that solves the one problem... thanks :)... the reason i wanted to have that last snippet was because in my one program i create some linked lists with objects of another class... and i want to be able to copy that linked list over to a queue

@Tim: In the current form it's not possible. If you use the code I posted then there is no relationship between LinkedList and Queue so you cannot assign a LinkedList to a Queue. Furthermore, if you extend LinkedList it's still not correct because then Queue is a specialized linked list and so cannot appear to the left of the assignment.
