    Default Checkout line Simulation

    So I have to program this MVC GUI of a checkout line. I have a gui that has 10 registers. Each register has a queue of customers. There is a button that when clicked, will generate a customer and the customer will be entered in the line with the shorted amount of people in the line. I have everything coded but the GUI. I'm not sure how to get the customer created.

    I guess where I would need help is in the StoreView and StoreController classes. I need help being able to use my methods and classes that I have created.

    Here are my classes:

    Store:

    import java.util.HashSet;
     
    public class Store {
     
    	private HashSet<Register> regs;
     
    	public Store(){
    		this.regs = new HashSet<Register>();
     
    		for(int i = 0;i<=10; i++){
    			regs.add(new Register());
    		}
    	}
     
    	private Register leastFullRegister() {
     
    		int minLineSize = Integer.MAX_VALUE;
    		Register leastFullRegister = null;
     
    		for ( Register r : regs ) {
    			if ( r.lineSize() < minLineSize ) {
    				minLineSize = r.lineSize();
    				leastFullRegister = r;
    			}
    		}
    		return leastFullRegister;
    	}
     
    	public String toString(){
     
    		String str = "";
     
    		for(Register r: regs){
     
    			str += r.toString();
    		}
    		return str;
    	}
     
     
    }

    Register:

    import java.util.LinkedList;
    import java.util.Queue;
     
    public class Register {
     
    	private boolean open; // line open or not?
    	private Queue<Customer> line; //the line of customers
     
     
    	public Register(){
    		open = true;
    		line = new LinkedList<Customer>();
    	} 
     
    	public double getTotalEnqueue(){
     
    		double totalTime = 0;
     
    		for(Customer cust: line ){
    			totalTime += cust.getServiceTime();	
    		}
     
    		return totalTime;
    	}
     
    	public void addCustomer(Customer c){
    		line.add(c);
    	}
     
    	public Customer pollCustomer(){
    		return line.poll();
    	}
     
    	public boolean isOpen(){
     
    		return open;
    	}
     
    	public void setOpen(boolean open){
     
    		this.open = open;
    	}
     
    	public int lineSize(){
    		return line.size();
    	}
     
    	public String toString(){
     
    		String str = "";
     
    		for(Customer cust: line )
    		{
    			str += "\n" + cust.toString();	
    		}
     
    		return str;
    	}
    }

    Customer:

    import java.util.Random;
     
     
    public class Customer {
     
    	private double serviceTime;
     
    	Customer(){
    		Random r = new Random();
    		serviceTime = r.nextInt(4);
    	}
     
    	public double getServiceTime(){
    		return serviceTime;
    	}
     
    	public void setServiceTime(double serviceTime){
     
    		this.serviceTime = serviceTime;
     
    		return;
    	}
     
    	public String toString(){
    		return "Service Time: " + serviceTime;
    	}
     
    }

    StoreView:

    import java.awt.Color;
    import java.awt.GridLayout;
    import java.util.ArrayList;
     
    import javax.swing.BorderFactory;
    import javax.swing.ImageIcon;
    import javax.swing.JButton;
    import javax.swing.JFrame;
    import javax.swing.JLabel;
    import javax.swing.JPanel;
    import javax.swing.JTextField;
     
    public class StoreView extends JFrame{
     
        private JPanel topPanel;
        private JPanel checkoutPanel;
     
        private JButton createCustomer;
     
        private JTextField[] totalServiceTime = new JTextField[10];
     
        private ImageIcon registerIcon;
     
        private JLabel[] registers = new JLabel[10];
     
        private ArrayList<Customer> customers = new ArrayList<Customer>();
     
        private StoreModel model;
        private Register register = new Register();
     
        public StoreView(StoreModel model){
            this.model = model;
     
            setTitle("Checkout Simulator");
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            setLayout(new GridLayout(11,10));
     
            buildTopPanel();
     
            add(topPanel);
            createRegisters();
            getServiceTime();
     
            pack();
            setVisible(true);
        }
     
        public void createRegisters(){
     
        	registerIcon = new ImageIcon("C:\\Users\\Dev\\Desktop\\GUI Project\\GuiProject\\src\\register.png");
     
        	for(int i = 0; i < registers.length; i++){
     
        		registers[i] = new JLabel();
        		registers[i].setIcon(registerIcon);
        		add(registers[i]);
        	}
        }
     
        public void getServiceTime()
        {
     
        	for(int i = 0; i < totalServiceTime.length; i++)
        	{
        		totalServiceTime[i].setText("" + register.getTotalEnqueue());
        		add(totalServiceTime[i]);
        	}
        }
     
     
        public void buildTopPanel(){
            topPanel = new JPanel();
            topPanel.setBorder(BorderFactory.createLineBorder(Color.BLACK, 1));
            createCustomer = new JButton("CreateCustomer");
            topPanel.add(createCustomer);
        }
     
        public void setCustomer(){
     
        }
    }

    StoreModel:

    public class StoreModel {
     
    	private Customer cust = new Customer();
    	private Store store = new Store();
    	private Register reg = new Register();
     
    	public StoreModel(){
    		setCustomer(new Customer());
    		setStore(new Store());
    		setRegister(new Register());
    	}
     
    	public StoreModel(Customer customer, Store store, Register register){
    		setCustomer(customer);
    		setStore(store);
    		setRegister(register);
    	}
     
     
    	public Customer getCustomer(){
    		return cust;
    	}
     
    	public void setCustomer(Customer customer){
    		cust = customer;
    	}
     
    	public Store getStore(){
    		return store;
    	}
     
    	public void setStore(Store store){
    		this.store = store;
    	}
     
    	public Register getRegister(){
    		return reg;
    	}
     
    	public void setRegister(Register reg){
    		this.reg = reg;
    	}
    }

    Store Controller:

    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
     
     
    public class StoreController {
     
    	private StoreModel model;
    	private StoreView view;
     
    	public StoreController(StoreModel model, StoreView view){
    		this.model = model;
    		this.view = view;
    	}
     
    	class AddCustomer implements ActionListener{
     
    		@Override
    		public void actionPerformed(ActionEvent e) {
    			model.getCustomer().getServiceTime();
     
    		}
     
    	}
    }

    We don't get paid, we give our time voluntarily. Making us wade through a butt-load of code and having to figure out what you want/need with only a vague description from you is not going to get you much help. The more specific your question is the more specific our answer will be.

    I never asked for a handout of code. I obviously have done the work here. I told you what was asked. Everything I typed above, has been implemented other than the GUI part. I said I don't know how to add a customer to the line using the Create Customer button.

    How many lines of code have you posted? For anyone to be able to help you they would have to spend a considerable amount of time getting familiar with your code. Time that could be better spent on something more intersting to us. I'm not trying to be a bastard. I'm just offering some tips on how you can improve your chances of getting help.

    What should I do then in order to get help because I really am at a point where I'm not sure what my next step? I realize I have a lot of code here, but I can't help that.
