Answer 1

google-http-java-client

Answer 2

Already answered, the answer is good, but in my free time I advise you to figure it out: jnetpcap.com ( How to use RAW sockets in Java? )
It will be difficult to figure it out, but if you figure it out, you can work with the network at the level of creating your own protocols, modifying existing ones, and in general a bunch of all sorts nishtyakov, because it allows you to build packages from scratch.
It will still come in handy sooner or later, and it will add a line in the resume that distinguishes it from other developers, transferring you immediately from the programmer section to "network programmer", which will certainly expand the possibility of employment, and the principles are identical with all other languages.
