How to set a delay on the execution of a KeyListener?

Question

Java

I need that when the button is pressed, the action occurs after a specific time
and the next press can be made after a while
For example: When you press D, the variable I increases by 1 after 2 seconds, and the next press will be available after 3 seconds

Answer 1

ExecutorService to help you, plus do disable on your button.

myBtn.setEnabled(false);
ExecutorService executor = Executors.newFixedThreadPool(10);
Runnable runnableTask = () -> {
    try {
        TimeUnit.MILLISECONDS.sleep(2000);
        myBtn.setEnabled(true);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
};
executorService.execute(runnableTask);
