SwingUtilities.invokeLater(Runnable) method

Question

Elaborate SwingUtilities.invokeLater(Runnable) method?

Answer 1

The stationary utility method invokeLater(Runnable) is proposed to execute a new runnable thread from a Swing application without disturbing normal sequence of the event forwarding from the Graphical User Interface (GUI). The method puts the runnable object in the queue of Abstract Windowing Toolkit (AWT) events which are due to be processed and returns directly. The runnable object's run() method is only called while it reaches at the front of the queue.
The deferred outcome of invokeLater(Runnable) method make sure that any necessary updates to the user interface can take place immediately, and the runnable work will begin as soon as these high priority events are allocated with. The invoke later method could be used to start the work in response to a button click which also needs a significant modification to the user interface, perhaps to control other activities, when the runnable thread executes.
