1. You are given the following Java Code. Write down the output that will be produced when it is executed. public class Maint public static void main(String[] args) { Queue queue = new Linkedlist>(); int[] arr = {7, 22, 31}; for(int x: arr) / for each Loop queue.add(x); System.out.println("queue.peek + queue.peek ()); queue.remove(); System.out.println("queue.peek + queue. peek()); queue.remove(); System.out.println("queue.peek + queue.peek()); Stack stack = new Stack>(); for(int x: arr) stack.add(x); " + stack.peek()); System.out.println("stack.peek = stack.pop(); System.out.println("stack.peek stack.pop(); System.out.println("stack.peek + stack peek ()); " + stack.peek())
