Assume that a stack has been declared and instantiated with the ArrayDeque class. Show the output produced by the following code fragment:

You should be able to do this by just thinking about it, but feel free to complete and run a program to check your answer.

stack.push('Z'); stack.push('Y'); System.out.println(stack.peek()); stack.push('X'); System.out.println(stack.pop()); stack.push('W'); while (!stack.is Empty()) ( 3 System.out.println(stack.pop()); System.out.println(stack.peek());
