In Java Swing, most component methods are not thread-safe, meaning they must be invoked from the Event Dispatch Thread (EDT) to avoid potential threading issues. However, there are a few exceptions where certain methods are explicitly documented as thread-safe and can be safely called from any thread. These thread-safe methods primarily include:
repaint() - This method can be called from any thread. It schedules a request for the component to be repainted, which will eventually be handled by the EDT[1][3][4][5].
revalidate() - Similar to repaint, this method can also be invoked from any thread. It is used to invalidate the layout of a container and schedule a call to validate()[1][3][4][5].
invalidate() - This method can be safely called from any thread. It marks the component as needing to be laid out again[3][5].
These methods are safe because they do not directly update the GUI but rather schedule the updates to be performed later by the EDT, thus avoiding direct interaction with the component's state from multiple threads. This approach minimizes the risk...
