Refer to the code fragment below and convert the following Queue
structure into a Stack structure. You should create a reference
called S1 for the stack structure.
Code:
Queue Q1 = new LinkedList ();
Q1.add(“Sandra”);
Q1.add (15);
Q1.add (200);
Q1.add (‘# ‘);
Q1. remove ();
System.out.println(Q1);
System.out.println(Q1.peek());
Q1.add(“Mary”);
System.out.println(Q1);
