I have my original text field in my first frame and I need it to be displayed in my other jframe. The code is:
JButton btnContinue = new JButton("Continue");
btnContinue.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String msg = nameL.getText();
frame2 fram = new frame2 ();
fram.setVisible(true);
frame.dispose();
new order (msg) .setVisible(true);
'nameL' is the textbox the user enters their name in.
This code describe where it should be displayed:
public order(String para){
getComponents();
JLabel lblNewLabel_1 = new JLabel("");
lblNewLabel_1.setBounds(91, 27, 254, 84);
contentPane.add(lblNewLabel_1);
lblNewLabel_1.setText(para);
this is my first class where the user inputs their name

Open both JFrames, have them listen to the EventQueue for a custom "string display" event.
Wrap the string to be displayed in a custom event.
Throw that on the event queue, allowing both the JFrames to receive the event, which they will then display accordingly.
---- Edited with an update ----
Ok, so you're a bit new to Swing, but hopefully not too new to Java. You'll need to understand sub-classing and the "Listener" design pattern.
Events are things that Components listen for. They ask the dispatcher (the Swing dispatcher is fed by the EventQueue) to "tell them about events" and the dispatcher then sends the desired events to them.
Before you get too deep in solving your problem, it sounds like you need to get some familiarity with Swing and its event dispatch, so read up on it here.

I have one Swing project and I have an action listener on JTextField for Tab key as follows.
There is a JOptionPane.showMessageDialog() inside the action listener. And when Tab is pressed option pane will show an Information message.
My problem is that, when I press Enter on OK button of Information Message dialog, a serie of action is invoked viz Tab action of JTextField and Enter action of btnNewButton.
If I use mouse click on OK button of Error Message dialog, every thing is fine and no problem.
Can I solve this using key bindings instead of key listener?
Please suggest a solution

The problem is that you are overriding method keyReleased(). The JOptionPane is closing before the keyReleased() method is called and since you make btnNewButton the focused component after the JOptionPane is closed, the keyReleased() method is invoked – which displays the other JOptionPane.
Simply rename the method to keyPressed().
Also, you don't need the dialog member. The first parameter to JOptionPane#showMessageDialog should be the JFrame.
Here is your code with my corrections.

Note that (at least in JDK 15) there is no need to explicitly set the default close operation for JFrame since the default is EXIT_ON_CLOSE

You're making the frame frame, of type GeneralWindow, visible. But you never add any component to that frame. Instead, your initialize method creates yet another frame, and adds many components to that frame. Don't create another frame, and add the components to this, instead.
In Your initialize() just change the frame to this keyword
e.g
//Remove this line
frame = new JFrame();
//change frame to this keyword
this.setBounds(100, 100, 450, 300);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.getContentPane().setLayout(null);
That its u r done...
Whilst the two answers provide here give a correct solution, they both reinforce the view that you should extend JFrame. This is not good advice in general, as you should favour composition over inheritance. Indeed the way you were writing the code to include a JFrame as a private member was the correct instinct.
I've included a stripped down version of your code that doesn't extend JFrame Instead it creates an instance of the JFrame when you call the createAndDisplayFrame() method.
public class GeneralWindow {
private JFrame frame;
private JButton orderButton;
public static void main(final String[] args) {
EventQueue.invokeLater(new Runnable() {
#Override
public void run() {
GeneralWindow window = new GeneralWindow();
window.crateAndDisplayFrame();
}
});
}
public void crateAndDisplayFrame() {
initialize();
frame.setVisible(true);
}
private void initialize() {
frame = new JFrame();
frame.setBounds(100, 100, 450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
orderButton = new JButton("Order");
orderButton.setBounds(309, 12, 115, 23);
frame.getContentPane().add(orderButton);
}
}
I created a console based program that allowed users to take a math quiz. The program basically generated random numbers and determined if the answer was right or wrong.
Now, I'm trying to create the GUI version of this program and I'm stuck.
I want to print text messages in the jtextarea from a different class. I've used the get and set methods, but for some reason it doesn't output the text messages. I've done some research on swing workers but I have no idea how to get it to work so I'm trying to avoid using it if possible.
This is not a homework assignment. I started learning java 4 months ago so i may not understand advance concepts.
I guess what I want to know... do I have to use swing workers? all really want to do is generate random numbers and output the result in the jtextarea... it shouldn't freeze the gui, right? Anyway, thanks in advance.

It would be much of a help,
Thank you :)
To switch between JFrames, call setVisible(true) for the JFrame you want to reveal and setVisible(false) for the one you want to hide. CardLayout doesn't apply here.
Suggestions: read the Swing tutorial on layouts, don't use null layouts with absolutely positioning, and familiarize yourself with the differences between ordinary containers and top-level containers.
So what I've got is that I would love to try and make an little login applet. I'm using Java Windowsbuilder for it, to make it easyer for me. I hope the code isn't to messy, because I'm just a starter.
The problem I've got is that My JButton "login" only registers a keyevent when it's selected trought tab, or when you first click it. What I want is that I can use the button always just by pressing the "ENTER" key.
Hope you guys solve my problem :)

Sounds like you want to make the "login" button the default button for the dialog.
See Enter Key and Button for the problem and solution.
When using panels KeyListeners won't work unless the panel is focusable. What you can do is make a KeyBinding to the ENTER key using the InputMap and ActionMap for your panel.
public class Sample extends JPanel{
//Code
Sample() {
//More code
this.getInputMap().put(KeyStroke.getKeyStroke((char)KeyEvent.VK_ENTER), "Enter" );
this.getActionMap().put("Enter", new EnterAction());
}
private class EnterAction extends AbstractAction(){
#Override
public void ActionPerformed(ActionEvent e){
//Acion
}
}
}
