code Help me with my Java project

[SavageNeo]

 

Longs story short, I need help. Im trying to make a "play again" button when the game says "Game Over", but I do not know how. Can anyone help? Code also attached to this post. You can edit the code all you like. The game is also attached to the attachments. Thank you.

Can you ask a more specific question? 
 

Unfortunately not a lot of people are going to download and try to understand your project, myself included.

 

 If you break down what you really want, it will be easier to help you

You can use the Java JButton class to create buttons. Something like (More info: AWT Button Class (tutorialspoint.com)

JButton replayButton = new JButton("Play Again");

replayButton.addActionListener(new ActionListener() {
	public void actionPerformed(ActionEvent e) {
		// Add button click logic here
	}
});

Panel buttonPanel = new Panel();
buttonPanel.add(replayButton);

 

More likely, you're looking for a button feature within the Java Graphics. You can create a more customized button and detect click within shapes like this:

Shape replayButton = new Rectangle2D.Double(100, 100, 100, 100);

addMouseListener(new MouseAdapter() {
  @Override
  public void mouseClicked(MouseEvent me) {
    super.mouseClicked(me);
    // Check if mouse is clicked within shape
    if (replayButton.contains(me.getPoint())) {
		// Add code for button click here
    }
  }
});
