Stacks = new Stack ();
Queueq = new LinkedList ();
s.push("how");
s.push("are");
s.push("you");
while (!s.isEmpty()) {
q.add(s.pop());
}
System.out.println(q);
2) Write the output produced when the following method is passed each of the following stacks:
public static void mystery1(Stack s) {
Queueq = new LinkedList ();
while (!s.isEmpty()) {
int n = s.pop();
q.add(n);
q.add(n);
}
while (!q.isEmpty()) {
s.push(q.remove());
}
System.out.println(s);
