"This is the International Edition. The content is in English, same as US version but different cover. Please DO NOT buy if you can not accept this difference. Ship from Shanghai China, please allow about 3 weeks on the way to US or Europe. Message me if you have any questions."
Good examples, easy to read and digest. Can definitely be used as a cookbook/reference in the future. I recommend it to anyone who is doing network development in Java in the future. It briefly discusses different types of concurrency and asynchronous programming.
Read to refresh my knowledge of Java, but it's too outdated & too many not necessary details - it looks like it was written for person, who're never heard about networking & related things...
