Difference between SwingUtilities Threads and AWT.EventQueue threads

Question

I am using using the Netbeans 7 IDE to develop a GUI desktop application. When I create the JFrame class , Netbeans uses the

java.awt.EventQueue.invokeLater(new Runnable() { }

To initiate the runnable object. But my application has swing components as well.

I will like to know the difference between the

 java.awt.EventQueue threads

and

SwingUtilities threads

for GUI application development.

`SwingUtilities.invokeLater` is still with us for historic reasons only, to maintain backwards compatibility. Apart from that, they are the same thing. — Marko Topolnik, May 28 '13 at 12:30

According to the doc here

As of 1.3 SwingUtilities.invokeLater() method is just a cover for java.awt.EventQueue.invokeLater().

Also the source of SwingUtilities here

public static void invokeLater(Runnable doRun) {
    EventQueue.invokeLater(doRun);
}

Both are actually the same. SwingUtilities.invokeLater directly calls EventQueue.invokeLater (ref).

As of 1.3 this method is just a cover for java.awt.EventQueue.invokeLater().
