How to start my program when I click start (button in frame) and slow it down so the loop isn't to fast?

Question

I'm creating a racing game and in my game I have 2 frames. One is the start screen and the second is where the race will take place. I have a button that takes me to my second frame. However the problem I am running into is that when I start the program the racing cood will start executing. my current solution is to have another button on the second frame to start the code, but when i do that the cars will teleport to the finish line without slowing down.

This is my code to fun the cars

play.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
    int r1 = 0;
    int r2 = 0;
   do {
       //car random num
         r1 = r1 + (int) (Math.random() * 10);
         r2 = r2 + (int) (Math.random() * 10);
         r3 = r3 + (int) (Math.random() * 10);
         r4 = r4 + (int) (Math.random() * 10);
         r5 = r5 + (int) (Math.random() * 10);
   //car1
   car1.setBounds((r1), (115), car1.getPreferredSize().width, car1.getPreferredSize().height);
   //car2
   car2.setBounds((r2), (165), car2.getPreferredSize().width, car2.getPreferredSize().height);

});

I have tried to use Thread.Sleep(_;but it doesn't work.

What the point of al those 5 randoms ? You are using only two of them (at least at the part of the code, you've showed) — Victor Gubin, Oct 22 '19 at 16:54

Try to put Thread.sleep() before your actionPerformed method and inside a try / catch, like this:

try {
   Thread.sleep(2000);
} catch (InterruptedException e) {
   e.printStackTrace();
}

And your do / while doesn't have while condition?

`Thread.currentThread().interrupt();` should be used to correctly handle InterruptedException – Victor Gubin Oct 22 '19 at 16:55
