Why should I use Swing Utilities and how to use it?

This mainly concerns my question here , but I do not understand why Swing Utilities is needed and what it is used for. I am developing a swing gui and I do not want to miss out on all that Swing Utilities has to offer. Also someone can explain what the method does invokeLaterand how it works.

In addition, as indicated in the API , it is invokeLaterused when the application thread needs to update the GUI.
