I need Help with list in my Lab 3

Lab3:

1) Create data storage for each “user” with the attached “Person.java” file.

2) Implement the CompareTo() method from the “Comparable” interface inside the Person class.

3) Store all the users in an arrayList of “Person” objects.

4) Use an enhanced for loop to iterate through the arrayList of person objects and then compare the “temp” Person from the user input.

5) In this version, only return zero if the objects match (meaning password=password, username=username, and studentID=studentID)

This is my Person.java File

public class Person{private String username;private String password;private Long StudentID;  public Person(String User, String Pass, Long ID){this.username = User;this.password = Pass;this.StudentID = ID;}    public String getPassword (){return this.password;}  public String getUsername(){return this.username;}    public Long getStudentID(){return this.StudentID;}}

This is my LOGIN.java file

import javax.swing.JFrame;import java.awt.BorderLayout;public class Login{public static void main(String[] args){LoginGUI cuFrame = new LoginGUI();cuFrame.setVisible(true);cuFrame.setTitle(“Login”);cuFrame.setSize(300,150);cuFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);  }}

This is my LOGINGUI.java

import java.awt.event.*;

import java.awt.event.KeyAdapter;

import java.awt.event.ActionListener;import java.awt.BorderLayout;import java.awt.Dimension;import javax.swing.border.*;import javax.swing.*;

public class LoginGUI extends JFrame{private JTextField txtUser;private JTextField txtPass;private JTextField txtStuID;private JLabel lblUser;private JLabel lblPass;private JLabel lblStuID;private String keep = “”;private String finalPassword = “”;private JButton btnLogin;private JButton btnExit;private JPanel panel1;  public LoginGUI(){setLayout(new BorderLayout(10,10));panel1 = new JPanel();panel1.setPreferredSize(new Dimension(250, 250));  txtUser = new JTextField();txtUser.setPreferredSize(new Dimension(150,20));  txtPass = new JTextField();txtPass.setPreferredSize(new Dimension(150,20));  txtPass.addKeyListener(new KeyAdapter() {public void keyTyped(KeyEvent arg0) {JTextField textField = (JTextField) arg0.getSource();keep += arg0.getKeyChar();String pressedKey = arg0.getKeyText(arg0.getKeyChar());String temp = “”;if (arg0.getKeyChar() == KeyEvent.VK_BACK_SPACE) {finalPassword = finalPassword.substring(0,finalPassword.length() – 1);for (int i = 0; i < finalPassword.length(); i++) {temp += “*”;}textField.setText(temp);} else if (“Enter”.equals(pressedKey)) {System.out.println(finalPassword);} else {finalPassword += (String.valueOf(arg0.getKeyChar()));  arg0.setKeyChar(‘*’);}} });txtStuID = new JTextField();txtStuID.setPreferredSize(new Dimension(150,20));lblUser = new JLabel(“Username: “);lblPass = new JLabel(“Password: “);lblStuID = new JLabel(“StudentID: “);  btnLogin = new JButton(“Login”);btnExit = new JButton(“Exit”);  panel1.add(lblUser);panel1.add(txtUser);panel1.add(lblPass);panel1.add(txtPass);panel1.add(lblStuID);panel1.add(txtStuID);panel1.add(btnLogin);panel1.add(btnExit);    ActionListener LoginAction = new LoginListener();btnLogin.addActionListener(LoginAction);    ActionListener ExitAction = new ExitListener();btnExit.addActionListener(ExitAction);add(panel1, BorderLayout.CENTER);

}  class ExitListener implements ActionListener{public void actionPerformed(ActionEvent event){System.exit(0);}}  class LoginListener implements ActionListener{public void actionPerformed(ActionEvent event){Validate V = new Validate();//String pw = txtPass.getText() ;if (!keep.matches(“.*[A-Z].*[0-9].*”) && keep.length() < 10 ){JOptionPane.showMessageDialog(null,”Your Password needs atleast one Captial Letter or One Number n Your Password must contain atleast 10 Characters “);}else if (keep.contains(“,”) || keep.contains(” “)){JOptionPane.showMessageDialog(null,”Your Password must not have Comma or Space”);}else if (V.Verify(txtUser.getText(), keep, txtStuID.getText())){JOptionPane.showMessageDialog(null,”Your user account has been validated!”);}else{JOptionPane.showMessageDialog(null,”Your Username or Password is incorrect. Please try again”);}  txtUser.setText(“”);txtPass.setText(“”);txtStuID.setText(“”);}}    }

This is my Validate.java file

import java.util.*;import java.io.*;import javax.swing.JOptionPane;class Validate{public Boolean Verify(String u, String p, String i){try{Scanner FileScan = new Scanner(new File(“USERDATA2.txt”));while (FileScan.hasNextLine()){String S=FileScan.nextLine();String[] Sa= S.split(“,”);if( (u.equals(Sa[0])) && (p.equals(Sa[1])) && (i.equals(Sa[2])) ){FileScan.close();return true;}}FileScan.close();}catch(IOException e){JOptionPane.showMessageDialog(null, e.getMessage());}return false;}}

This is my USERDATE2.txt if you need it

USER1, fBqj!P4B33, 900000003USER2, 2Hmkq98NW+, 900000006USER3, _SNT8wsz85, 900000009USER4, 5LDz2H%t3t, 900000013USER5, at!tbX92FC, 900000016USER6, Kevin123456, 900
