Why should the implementation of any swing callback (like a listener) execute quickly?..

Answer / Anupam Raj

"The implementation of a Swing callback, such as an event listener, should be designed to execute quickly because they are executed on the Event Dispatch Thread (EDT). Updating the UI or performing time-consuming operations on the EDT can lead to unresponsive applications. Therefore, it's crucial to perform any CPU-intensive tasks off the EDT using SwingWorker or other threading mechanisms."n
