)Because this chapter is a part of the network programming in Java, it synthesizes the knowledge of threads and windows, and is more comprehensive. The idea of design is more comprehensive, experience the importance of basic knowledge, and the test in class, the experiment under the class is also more difficult. Hope to be able to persist in learning, and be able to regularly consolidate the previous knowledge, improve their Java programming ability.Learning progress Bar
