Question

I want to make a method wait until an ActionEvent method has processed before continuing.
Example:

public void actionPerformed(ActionEvent evt) {

    someBoolean = false;

}

the actionPerformed method is linked to a textField I have, and the method is triggered when you press Enter. What I want to do, is have a different method pause until the actionPerformed method happens.
Example:

public void method() {

    System.out.println("stuff is happening");
    //pause here until actionPerformed happens
    System.out.println("You pressed enter!");

}

Is there a way to do this?

Answer 1

CountDownLatch should do the trick. You want to create a latch waiting for 1 signal.

Inside the actionPerformed you want to call countDown() and inside “method” you just wanting to await().

-edit-
I’m assuming that you’ve already got the right amount of Threads set up to handle the situation.
