What is the output of the following Java code? public class CircularQueue protected static final int CAPACITY = 100; protected int size,front,rear; protected Object q[]; int count = 0; public CircularQueue() this(CAPACITY); public CircularQueue (int n) size = n; front = 0; rear = 0; q = new Object[size]; public void enqueue(Object item) if(count == size) System.out.println("Queue overflow"); return; else q[rear] = item; rear = (rear+1)%size; count++; public Object dequeue() if(count == 0) System.out.println("Queue underflow"); return 0; else Object ele = q[front]; q[front] = null; front = (front+1)%size; count--; return ele; public Object frontElement() if(count == 0) return -999; else Object high; high = q[front]; return high; public Object rearElement() if(count == 0) return -999; else Object low; rear = (rear-1)%size; low = q[rear]; rear = (rear+1)%size; return low; public class CircularQueueDemo public static void main(String args[]) Object var; CircularQueue myQ = new CircularQueue(); myQ.enqueue(10); myQ.enqueue(3); var = myQ.rearElement(); myQ.dequeue(); myQ.enqueue(6); var = mQ.frontElement(); System.out.println(var+" "+var);
