	public void queueExample() {
 
		Queue queue = new LinkedList();
 
		queue.add("item1");
		queue.add("item2");
		queue.offer("item3");
		queue.offer("item4");
 
		System.out.println("remove: " + queue.remove());
		System.out.println("element: " + queue.element());
		System.out.println("poll: " + queue.poll());
		System.out.println("peek: " + queue.peek());
	}
 
	public static void main (String [] args) {
		new Main() queueExample();

Full disclosure- I'm not a mod. Do what you want, but keep in mind that you should probably be making it easier for people to help you, not harder.

Sorry kev i accidentally clicked the submit :[
okay. sorry sorry

This is quite uninformative as to the problem...does it compile? Are there exceptions?

Ran unchanged for me. Please post how you are attempting to run your code, and any errors.
