Java provides two classes for the TCP protocol, which are used in client programming and server-side programming, respectively. Before the application begins to communicate, you need to create a connection that is initiated by the client program, and the server-side program needs to listen to the host's specific port number and wait for the client to connect. In

Java Learning (12), object-oriented programming (4) Inheritance, concepts and super keywords, object-oriented programming super Inheritance Concept: ① The idea behind inheritance is to build new classes based on existing classes; ② When an existing class is inherited, its methods and attributes are reused.

Threads are a sequence of task control flows in a process, and multithreading is the foundation of concurrent programming because process creation and destruction require destroying large amounts of resources and multiple threads can share process data. Multi-core CPU can realize the implementation of multiple tasks in parallel, single core CPU program is not really parallel operation, but through the time slice switch to execute, because the time sli
