Swing literature?

Question

Java

Throw, please, or give links to literature on swing, preferably in English, by the way, taking this moment, I want to ask if it is worth reading for general development https://github.com/SamyPesse/How-to-Make-a-Compute ... , or there it will be necessary to specifically understand, otherwise I think that it will be useful for a general understanding of the operation of the OS.
