, with final type processing, we only need to implement the thread safety of the map through a shallow copy of the collections.Examples we do not provide, you can go back to try to write, the next section we are discussing.Implementing concurrent Add functionality with existing thread-safe classesThere are many such classes in the Java API, such as vectors, Hashtable, and so on, let's look at an example.Package Com.gome.qiantai.tools;import Java.util.vector;import com.gome.qiantai.service.iappra

Singleton design pattern: Resolves a class that only has one object in memory.(1) Want to ensure that the object is unique.A) to avoid excessive creation of such objects by other programs. Prevent other programs from setting up this type of object firstb) Also for other programs to have access to the class object, in this class, you can customize an object.c) To facilitate the access of other programs to custom objects, you can provide some external access.(2) How do these three parts show up in

The socket is also called a socket, and the application usually makes a request to the network through a "socket" or answers a network request.Java has simplified the programming interface for sockets. Java provides serversocket to support it. In fact, when creating an instance object of the class and providing a port resource, a fixed location can be set up for other computers to access, such as: ServerSocket server=new serversocket (6789);A little note here is that the allocation of the port m
