Here is the whole applet:
package wages;
/**
* Insert the type's description here.
* Creation date: (10/4/2003 6:50:44 PM)
* @author:
*/
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.io.*;
import javax.swing.*;
/**
* Insert the type's description here.
* Creation date: (10/2/2003 8:02:27 PM)
* @author:
*/
public class Login extends javax.swing.JFrame implements java.awt.event.ActionListener
{
private UserRecord root;
Wages myWages = new Wages("Wages");
Button ok = new Button("OK");
Button cancel = new Button("Cancel");
Label user = new Label("Username:");
Label pass = new Label("Password:");
TextField userField = new TextField();
TextField passwordField = new TextField();
JPanel buttonPanel = new JPanel();
JPanel inputPanel = new JPanel();
JPanel resultPanel = new JPanel();
int tries = 0;
String username;
String password;
public Login() {
ok.setActionCommand("1");
cancel.setActionCommand("2");
ok.addActionListener(this);
cancel.addActionListener(this);
inputPanel.add(userField);
inputPanel.add(passwordField);
inputPanel.setLayout(new GridLayout(1,1));
resultPanel.add(user);
resultPanel.add(pass);
resultPanel.setLayout(new GridLayout(1,1));
buttonPanel.add(ok);
buttonPanel.add(cancel);
buttonPanel.setLayout(new GridLayout(1,1));
getContentPane().add(resultPanel);
getContentPane().add(inputPanel);
getContentPane().add(buttonPanel);
getContentPane().setLayout(new GridLayout(3,2));
load();
passwordField.setEchoChar('*');
}
/**
* Invoked when an action occurs.
*/
public void actionPerformed(java.awt.event.ActionEvent e) {
String X = e.getActionCommand();
String action = new String();
char command = X.charAt(0);
switch (command)
{
case '1':
if (passwordchk()){
myWages.setSize(800, 600);
myWages.show();
}
else
{
JOptionPane.showMessageDialog(null, "Error, enter username and password again", "Error",JOptionPane.ERROR_MESSAGE);
tries++;
if (tries == 3){
System.exit(0);
userField.setText("");
passwordField.setText("");
}
}
break;
case '2': System.exit(0); break;
}
}
public void addnode(String name, String password)
{
UserRecord theNode = new UserRecord( name,
password,
null );
theNode.setNext( root );
root = theNode;
}
public void load(){
try {
String userfile = "c:\\ReadinAndWritin.NBi";
ObjectInputStream userin = new ObjectInputStream(new FileInputStream(userfile));
String[][] info = (String[][]) userin.readObject();
userin.close();
username = info[0][0];
password = info[0][1];
addnode(username,password);
} catch (IOException e) {
} catch (Exception e) {
}
}
public static void main(String[] args) {
Login window = new Login();
window.setTitle("Log In");
window.setSize(250, 150);
window.setVisible(true);
}
public boolean passwordchk(){
boolean passed = false;
String usernameField = userField.getText();
String passField = passwordField.getText();
if ((usernameField.equals("default")) & (passField.equals("firsttime")))
{
passed = true;
}
else {
UserRecord temp;
temp = root;
while (temp != null)
{
if ((usernameField.equals(username)) & (passField.equals(password)))
{
passed = true;
}
temp = temp.getNext();
}
}
return passed;
}
}
As you can see, if the password is correct (case 1), it will show up another class. So, i want to hide this logging applet. how do i do it?
thank you
