Re: Password Tester GUI HELP
Okay, so here is the code I have.
import java.awt.*; // for layout managers import java.awt.event.*; // for event handling import javax.swing.*; // for GUI components public class PasswordCheck extends JFrame { private LaxPanel laxPanel; private StrictPanel strictPanel; public PasswordCheck() { super("Password Checker"); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Container contentPane = getContentPane(); contentPane.setLayout(new BorderLayout()); JPanel northPanel = new JPanel(); northPanel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10)); contentPane.add(northPanel, BorderLayout.NORTH); String instructions = "<html>Welcome to Password Tester.<br>" + "Choose how you want to evaluate your password,<br>" + "enter it below, and click evaluate</html>"; northPanel.add(new JLabel(instructions, JLabel.CENTER), BorderLayout.NORTH); JPanel centerPanel = new JPanel(new GridLayout(0, 3, 10, 10)); centerPanel.setBorder(BorderFactory.createEmptyBorder(0, 10, 0, 10)); contentPane.add(centerPanel, BorderLayout.CENTER); laxPanel = new LaxPanel(); centerPanel.add(laxPanel); strictPanel = new StrictPanel(); centerPanel.add(strictPanel); JPanel southPanel = new JPanel(); southPanel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10)); contentPane.add(southPanel, BorderLayout.SOUTH); JButton evaluate = new JButton("Evaluate"); southPanel.add(evaluate); evaluate.addActionListener(new Listener()); pack(); setVisible(true); } private class Listener implements ActionListener { public void actionPerformed(ActionEvent event) { evaluation(); } } private void evaluation() { String lax = laxPanel.getLax(); String strict = strictPanel.getStrict(); if (lax == null && strict == null) { JOptionPane.showMessageDialog(this, "You need to select either lax or strict evaluation.", "PasswordCheck", JOptionPane.ERROR_MESSAGE); } else { JOptionPane.showMessageDialog(this, ("Your password is secure"), "PasswordCheck", JOptionPane.INFORMATION_MESSAGE); } } public static void main(String[] args) { new PasswordCheck(); } }
import javax.swing.*; public class LaxPanel extends JPanel { private JRadioButton laxButton; public LaxPanel() { setLayout(new BoxLayout(this, BoxLayout.Y_AXIS)); laxButton = new JRadioButton("Lax evaluation"); add(laxButton); } public String getLax() { if (laxButton.isSelected()) return "lax button"; else return null; } }
import javax.swing.*; public class StrictPanel extends JPanel { private JRadioButton strictButton; public StrictPanel() { setLayout(new BoxLayout(this, BoxLayout.Y_AXIS)); strictButton = new JRadioButton("Strict evaluation"); add(strictButton); } public String getStrict() { if (strictButton.isSelected()) return "Strict button"; else return null; } }
from here I need to make it so only one radio button can be chosen, but since they are on different panels I don't think I can add a button group. I also need to put in a user input box above the evaluate button so the user can input their password. Then I need to evaluate if their password is strong or not based on the criteria above.
Re: Password Tester GUI HELP
Are you asking how to make sure that they don't have lax and strict on at same time?
If so, use ButtonGroup.
ButtonGroup group = new RadioButtonGroup(); JRadioButton lax = new JRadioButton("Lax"); JRadioButton strict = new JRadioButton("Strict"); group.add(lax); group.add(strict);
Now you can select "Lax" or "Strict", but not both.
And selecting "Lax" automatically deselects "Strict" and selecting "Strict" automatically deselects "Lax".

Re: Password Tester GUI HELP
yeah, but they are in two different panels. Is there a way to keep the panels separate like i have them and make it so they are in a buttongroup?
