Should I use Swingutilities.invokeLater if I don’t directly extend Jframe?

Question

Hello. I understand that people use the method invokeLater of SwingUtilities when extending directly the class JFrame and initialize it in the method main. But what if I happen to have one JFrame as an attribute within a class which does not extend any other class, I must still use this method, no matter where exactly the JFrame, but because it is present in the code?

Answer 1

invokeLater

Causes runnable to have its method of execution called in the dispatch chain of the Eventqueue system. This will happen after all pending events are processed.

Other explanations: here

Basically Swing uses Event dispatching thread. The run method will be called at the end of the process of all events of the graphical interface.

But it doesn’t need to be implemented just because you have a Jframe within your class.
