For this assignment, you need to develop numberqueue adt (numberqueue. java). we assume each number in the queue represent a person in the line waiting for being served at your restaurant. based on historical data, you found that on average, one customer arrives at your restaurant on every five minutes interval, and it takes 3 minutes to serve each customer. write a tester program, named queuesimulation. java, to simulate the queue for 8 hours, then print the longest queue size during the 8 hours operation. did anyone leave your restaurant because the line if full? (assume the maximum capacity of the line is 10 people)
given: numberqueue. java

public class numberqueue{

private int[] data;
private int front, rear, numberofitems, capacity;
public numberqueue(int cap){
front=rear=numberofitems=0;
data=new int[cap];
capacity=cap;
}
public boolean isempty(){
return numberofitems==0;
}
public boolean isfull(){
return numberofitems==capacity;
}

public int size(){
return numberofitems;
}
public void enqueue(int val){
if(! {
data[rear]=val;
rear= ++rear % capacity;
numberofitems++;
}else{
system. out. println("it is full, find another restaurant! ");
}
}
public int dequeue(){
