1	public void add(E elem){
02	   //if we don't have any elems in our LinkedList
03	   if(head == null){
04	   head = tail = new Node<E>();
05	    head.elem = elem;
06	   head.next = tail;
07	   tail = head;
08	}

Is line 7 here in this case redundant since we have already made this assignment on line 4? Or am I missing something here?

Lines 4 and 7 both leave the nodes head and tail being equal, but the lines between (5 and 6) change the state of one of them (head) leaving them different. So line 7 equates them again.

hi guys

i did the functions as same and it compiles

but when i test it the program gives me an random output

how can i fix it ?

and i hope somebody can send me the code file and today please.

Perhaps start a thread, in the language forum, with your code and errors. If you are not getting the right output then explain what you are inputting, what you are getting back, and what you think you should get back.

Also observe the rules about asking for people to do your work for you. Hint - that is a no-no.
