Create a function that sorts an arraylist of objects

[Stavrosgr]

Hey , i need help with creating a function that sorts objects in an ascending order in the class ClientQueue.I've tried to do a lot of times but all i get is erros...The function is called addClient and,everytime it's called, it has to add a Client object in the correct order in the arraylist.The class Client contains a variable called priority and the arraylist is sorted according to the priority of the clients.The related codes are the following;

public class Cashier {

    private boolean open;
    private Client queue;
    Client currentClient;
    int serviceTime;
    int idleTime;

    public Cashier(boolean open) {
        this.open=open;
    }

import java.util.Random;
public class Client {
    public int priority;
    private int numItems;
    private double paysCash;
    
    public Client(int i) {
    int creationTime=i;
    int MAX_TIME=43200;
    Random rnd=new Random(); 
    numItems=rnd.nextInt(49)+1; //plh8os eidwn
    final int P_PAYS_CASH=rnd.nextInt(10);
    int P_IS_SPECIAL=rnd.nextInt(10);
    if(P_IS_SPECIAL>1) {
        priority=creationTime;
    }
    else {
            priority=creationTime-MAX_TIME;
        }
    }

You have no ClientQueue class.
There is no array.
Or even an attempt at the addClient() method.

When you have done what Tolls said, look up implementing comparable, compareTo(x other) and Collections.sort() this will give you your answer.
