    Default Getting rid of Extra Dialog Boxes

    I'm currently working on some code for an applet and I have it up and working but am trying to get rid of the extra JOptionPane Message Dialogs and replace them with just a simple JLabel within the already running applet.

    Here is my current code:

    import javax.swing.*;
     
    import java.awt.event.*;
    import java.awt.*;
     
    public class JPasswordC extends JApplet implements ActionListener {
     
        Container PW = getContentPane();
        JLabel password = new JLabel("Enter Password(and click OK):");
    	 Font font1 = new Font("Times New Roman", Font.BOLD, 18); 
        JTextField input = new JTextField(7);
        JButton enter = new JButton("OK");
     
        public void start() {
            PW.add(password);
    		  password.setFont(font1);
            PW.add(input);
            PW.add(enter);
            PW.setLayout(new FlowLayout());
            enter.addActionListener(this);
        }
     
        public void actionPerformed(ActionEvent e) {
            String pass1 = input.getText();
            String passwords[] = {"Rosebud", "Redrum", "Jason", "Surrender",  "Dorothy"};
           for(int i=0;i<passwords.length;i++) {
               if (pass1.equalsIgnoreCase(passwords[i])) {
                JOptionPane.showMessageDialog(null, "Access Granted");
            }
      			 else {
           JOptionPane.showMessageDialog(null, "Access Denied");
            	}
    		}
        }

    The part I'm trying to isolate is in the actionPerformed after the array runs. I currently have it having the Message Dialogs popping based on the if else statement but as I mentioned prior I'd rather clean it up and just add a JLabel to it.

    get rid of the extra JOptionPane Message Dialogs and replace them with just a simple JLabel
    Where is the JLabel that is to show the message?
    Have you tried replacing the dialogs with using the JLabels?

    Well I just went in and tried

     public void actionPerformed(ActionEvent e) {
            String pass1 = input.getText();
            String passwords[] = {"Rosebud", "Redrum", "Jason", "Surrender",  "Dorothy"};
           for(int i=0;i<passwords.length;i++) {
               if (pass1.equalsIgnoreCase(passwords[i])) {
                JLabel response = new JLabel("Access Granted");
            }
    			  else		  
        			{  		
    				JLabel response = new JLabel("Access Denied");
       			}
     
    			PW.add(response);
    			} 
    	 }

    but it doesn't show the response regardless of the input dialog. I want the dialog to appear after the OK button, hmm.

    Can you post some code that compiles and executes and shows the problem?

    After changing the contents of a container you need to have the container re-do its layout so the new group of components are displayed.

    I'm not quite sure which part of the code you want since I had posted all of it in my prior comments.

    When running the applet it displays and I enter the correct password to test it but instead of displaying a new JLabel it just stays blank as showing in my attached screenshot

    post #1 has the JOptionPane code
    Post #3 is not a complete program that can be compiled and executed.
    You need to post a complete version of the new code. The reason is that there have been many cases where OPs make changes to some of the code and don't post all of the changes. If a complete program is posted the chances are better that it will be up-to-date and not missing some changes.
    If you don't understand my answer, don't ignore it, ask a question.

    Ah see that makes sense. Well thank you, I tinkered with the code some more and found the solution, I had to create a setText within the if else statement. Corrected Code is below if you're interested. Thank you for the help.

    import javax.swing.*;
    import java.awt.event.*;
    import java.awt.*;
     
    public class Password extends JApplet implements ActionListener {
     
        Container PW = getContentPane();
        JLabel password = new JLabel("Enter Password(and click OK):");
        JLabel message = new JLabel();
        Font font1 = new Font("Times New Roman", Font.BOLD, 18); 
        JTextField input = new JTextField(7);
        JButton enter = new JButton("OK");
     
        public void start() {
            PW.add(password);
            password.setFont(font1);
            PW.add(input);
            PW.add(enter);
            PW.add(message);
            PW.setLayout(new FlowLayout());
            enter.addActionListener(this);
        }
     
        public void actionPerformed(ActionEvent e) {
            String pass1 = input.getText();
            String passwords[] = {"Rosebud", "Redrum", "Jason", "Surrender",  "Dorothy"};
            for(int i=0;i<passwords.length;i++) {
                if (pass1.equalsIgnoreCase(passwords[i])) {
                    message.setText("Access Granted");
                                return;
                }
                else {
                    message.setText("Access Denied");
     
                }
            }
        }
    }
