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();
}
}
}
