Java Swingworker Thread

Question

I have a question to ask about Java Concurrency. I do Java Threading. I am creating a simple interface that has a button and JSlider in it. Therefore, when I click the button, the variable will increase, and JSlider will move accordingly. Now I wonder if Swingworker is the right choice.

Answer 1

All you need to do is use SwingWorker for long-term tasks. What you describe will be done instantly. Therefore, you can do this in Thread Dispatch Thread, where all ActionListeners are executed.

Answer 2

First you can profile save your code.

• Examples when a state change does not block EDT: here and here .

• An example where an action can block EDT: here .

• An example in which an action blocks EDT: here .
