    Default Password Field Help.

    Following an tutorial I manage to create a screen that will ask for a Username and a password, but my purpose is not to create a login screen is to capture the info that the user put over there.

    Here is my code:

    //By Josť D. HernŠndez, 2013.
     
    import java.awt.BorderLayout;
    import java.awt.Container;
    import java.awt.event.KeyEvent;
    import javax.swing.JFrame;
    import javax.swing.JLabel;
    import javax.swing.JPanel;
    import javax.swing.JPasswordField;
    import javax.swing.JTextField;
     
    public class passwordpr 
    {
    	public static void main(String args[]) 
    	{
    		String title = "La Union";
    		JFrame frame = new JFrame(title);
    		Container content = frame.getContentPane();
     
    		JPanel userPanel = new JPanel(new BorderLayout());
    		JLabel userLabel = new JLabel("Username: ");
    		userLabel.setDisplayedMnemonic(KeyEvent.VK_U);
    		JTextField userTextField = new JTextField();
    		userLabel.setLabelFor(userTextField);
    		userPanel.add(userLabel, BorderLayout.WEST);
    		userPanel.add(userTextField, BorderLayout.CENTER);
     
    		JPanel passPanel = new JPanel(new BorderLayout());
    		JLabel passLabel = new JLabel("Password: ");
    		passLabel.setDisplayedMnemonic(KeyEvent.VK_P);
    		JPasswordField passTextField = new JPasswordField();
    		passLabel.setLabelFor(passTextField);
    		passPanel.add(passLabel, BorderLayout.WEST);
    		passPanel.add(passTextField, BorderLayout.CENTER);
     
    		JPanel panel = new JPanel(new BorderLayout());
    		panel.add(userPanel, BorderLayout.NORTH);
    		panel.add(passPanel, BorderLayout.SOUTH);
    		content.add(panel, BorderLayout.NORTH);
     
    		frame.setSize(250, 150);
    		frame.setVisible(true);
    	}
    }

    How can I capture the info that the user input in "Username" and "password"? Thanks. and much more specials to Norm.

    I hope you guys are not tired of me.

    The classes where the user enters the data have methods you can call to get the data.
    One way to know when the user has finished entering the data is to have a button that he can press.
    Add a listener to the button which will be called when the user presses the button.
    The listener method can then call the methods for the classes where the user has entered the data to get what was entered.

    See the tutorial: How to Write an Action Listener (The Java™ Tutorials > Creating a GUI With JFC/Swing > Writing Event Listeners)
    If you don't understand my answer, don't ignore it, ask a question.
