Having problems with Queues, any help ad I would be great full!

I have three classes, a customer, bank and a bankQueue.

Customer:

Code :

---

public class Customer
{
    int time;
    String tags;
 
    public Customer(int time, String tags)
    {
        this.time = time;
        this.tags = tags;
    }
}

---

BankQueue:

Code :

---

public class BankQueue
{
    int front, rear;
    Object[] queue;
 
    public BankQueue(int initialCapacity)
    {
        if (initialCapacity < 1)
            throw new IllegalArgumentException
            ("initialCapacity must be >= 1");
            queue = new Object [initialCapacity + 1];
            front = rear = 0;
    }
 
    public BankQueue()
    {
        this(4);
    }
 
    public void put(Object theObject)
    {
        if ((rear + 1) % queue.length == front)
        {
            Object[] newQueue = new Object[2* queue.length];
            int start = (front + 1) % queue.length;
            if(start < 2)
                System.arraycopy(queue, start, newQueue, 0, queue.length -1);
            else
            {
                System.arraycopy(queue, start, newQueue, 0, queue.length -start);
                System.arraycopy(queue, 0, newQueue, queue.length -start, rear +1);
 
 
            }
            front = newQueue.length -1;
            rear = queue.length -2;
            queue = newQueue;
        }
        rear = (rear +1) % queue.length;
        queue[rear] = theObject;
    }
}

Now if I test this and make a BankQueue and make a Customer, add the customer to the bankQueue, then the customer will be added.

I now have a bank class:

Code :

---

import java.util.Queue;
 
public class Bank
{
    BankQueue queue = new BankQueue();
 
    public Bank()
    {
 
    }
 
    public void Arrive(Customer customer)
    {
        queue.put(this);
    }
}

---

What I am trying to do, is when a customer goes to the bank (class) I will call method arrive, then this will send the customer to my BankQueue class. At the moment it just creates a new queue.

Thank you

So what should it do next?

Then ask yourself, "What steps will I take to perform that task?", and write those steps down.

Use those steps as a guide to write the code with. Ask for help if you get stuck

That's what I have tried to do.
I know that in my method arrive it calls the put method from BankQueue but does not add it to that queue that I want.

steps include:
customer object created
Customer arrives (method called in bank)
pass that customers information into the put option which then adds the customer into the queue. (wrong queue)

I have a feeling that : BankQueue queue = new BankQueue();

may be wrong?

I'm not trying to create another queue.
