Importance of time

my code-import java.util.*; class Queue { protected int size; protected int front; protected int[] data; public Queue() { this.size = 0; this.front = 0; this.data = new int[5]; } public Queue(int cap) { this.size = 0; this.front = 0; this.data = new int[cap]; } public int size() { return size; } public boolean isEmpty() { return (size == 0); } public void enqueue(int item) throws Exception { if (this.size() == this.data.length) { int[] oa = this.data; int[] na = new int[oa.length * 2]; for (int i = 0; i < this.size(); i++) { int idx = (i + front) % oa.length; na[i] = oa[idx]; } this.data = na; this.front = 0; } // if (this.size == this.data.length) { // throw new Exception(“queue is full”); // } this.data[(front + size) % this.data.length] = item; size++; } public int dequeue() throws Exception { if (this.size == 0) { throw new Exception(“queue is empty”); } int rv = this.data[front]; front = (front + 1) % this.data.length; size–; return rv; } public int getFront() throws Exception { if (this.size == 0) { throw new Exception(“queue is empty”); } int rv = this.data[front]; return rv; } public void display() { System.out.println(); for (int i = 0; i < size; i++) { int idx = (i + front) % this.data.length; System.out.print(this.data[idx] + " "); } System.out.print(“END”); } public static int ImpofTime(Queue q,int[] orig_order) throws Exception{ int tt=0; int job=0; int extime=0; while(!q.isEmpty()){ job=q.getFront(); } if(job==orig_order[extime]){ q.dequeue(); extime++; tt++; } else{ q.dequeue(); q.enqueue(job); tt++; } return tt; } static Scanner scn = new Scanner(System.in); public static void main(String[] args) throws Exception { Queue q = new Queue(); int n = scn.nextInt(); int[] process = new int[n]; for (int i = 0; i < n; i++) { q.enqueue(scn.nextInt()); } for(int i = 0;i < n;i++){ process[i] = scn.nextInt(); } System.out.print(ImpofTime(q,process)); } }

Hey @Vaishali-Varshney-544592352791244 just change class Name Queue to Main
