Alternative solution on randomizing JLabel

So, I have this task where the user guess the correct number just by clicking on the JLabel I have presented for them. What I was trying to is to generate a random number then use if (e.getSource() == random) { } but it seems object and int isn't a compatible operand and I was hoping if someone has any solution to this.
Anyways, here is the source code of what I am doing nothing good since I don't have any solution on my first problem yet.

MouseEvent#getSource will return the object which trigged the event, in your case, the JLabel.
A "generally" better solution might be to use JButton instead, then take advantage of the ActionListener. I'd attach a single ActionListener to the "correct" button to handle the correct workflow and a ActionListener to the others to handle the incorrect state

Set JPanel transparent for keypad

I'm actually codding a keypad for an application and I'm encountering a problem. I'm using some empty space in the JDialog I'm creating to place an exist button on the top right corner of the Dialog box. This empty space is creating a border to the dialog box which is unpleasant to see. So I've tried to make panels transparent with setOpaque(false) function, but I achieved nothing. Do I have to use the paint function (which I don't know how to use) ?
Here is my test function without the setOpaque tests I've done :

Simple example for making a JFrame transparent:
import java.awt.*;
import static java.awt.GraphicsDevice.WindowTranslucency.TRANSLUCENT;
import javax.swing.*;
class TransparentFrame extends JFrame
{
public TransparentFrame()
{
JPanel panel = new JPanel();
panel.setOpaque( false );
panel.add( new JButton("Button") );
add(panel, BorderLayout.SOUTH);
setUndecorated(true);
setSize(300, 300);
//pack();
// setOpacity(0.5f); // set transparency on frame and components
setBackground( new Color(0, 0, 0, 64) ); // set transparency on frame only
setTitle("Transparent Frame Demo");
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
}
public static void main(String args[])
{
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = ge.getDefaultScreenDevice();
// Exit when translucent windows aren't supported
if (!gd.isWindowTranslucencySupported(TRANSLUCENT))
{
System.err.println( "Translucency is not supported" );
System.exit(0);
}
// Create the GUI on the event-dispatching thread
SwingUtilities.invokeLater(() -> new TransparentFrame().setVisible(true));
}
}

Position Not Moving Despite of Key Listener

I made the Card Layout Working completely fine but what happened now is I added a keylistener to the object character which is a JLabel so whenever the person presses up the character should move up but it does absolutely nothing!
I also tried replacing it with a button which moves it when clicked and it worked completely fine. Also I tried changing the event meaning I changed that if they press up then the image of the town map would change but still no effect so it seems there is something wrong with my KeyListener

Add following code in your programme.
public static JPanel mainmenu = new JPanel();
public static JPanel loginpanel = new JPanel();
or initialize mainmenu & loginpanel before adding them into the game panel.

when you call game.add(loginPanel, "2") loginPanel is null

Passing info from one Jframe to another

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.

Why does my JRadioButton not work in this case?

I'm trying to create a screen to change the options of my game, so I'd a problem that using a JRadioButton works in a case and not in the other, and I didn't understand why... Does anybody know what happened?

Group the radio buttons like

playOptionsButtonGroup.add(radioPlayersNo);
playOptionsButtonGroup.add(radioPlayersYes);
playOptionsButtonGroup.add(radioSoundYes);
playOptionsButtonGroup.add(radioSoundNo);
