TCP ProgrammingUsing the socket (socket) in Java to complete the development of TCP programs, using this class can easily establish a reliable, bidirectional, continuous, point-to-point communication connection.In the socket program development, the server side uses ServerSocket to wait for the client connection, for the Java Network program, each client uses a socket object representation.In the
The runtime is programmed to resemble Java-like reflection. The comparison between runtime programming and Java reflection is as follows: 1. Features that can be implemented at the same point: getting class information, property set fetching, dynamic loading of classes (nsclassfromstring (@ "ClassName")), dynamic invocation of methodshere are the related usage me
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

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. You can also add new methods and attributes to customize

Code reuse is not enough to copy and change the code, but also to use classes without damaging the existing program code.
In java, code reuse can be divided into the following three types: comb
