201621123057 Java Programming 13th Week of study summary

1. Summary of this week's study

Summarize multiple web-related content in the way you like (mind Mapping, OneNote, or others).

2. Add network functions to your system (shopping cart, library management, landlords, etc.)-group complete

To allow your system to be used by multiple users over the network, you need to add network functionality to your system.

2.1 What network functions do you want to add to your system? What is the design idea?

For:
The class was added to enable the ThreadedServer remote operation of the code and create a new inner ThreadedHandler class to implement the multi-threading, which implements the Runnable interface and the corresponding operation in its run method.

2.2 What information does the system pass through the network? What is the format of the information?

For:
The information is stored using InputStream, OutputStream, and then packaged with scanner, PrintWriter.

2.3 Does your network module use TCP or UDP technology? What are the common classes in a module?

For:
TCP technology is used;
Common classes are ServerSocket classes, classes Socket , Runnable classes, and Thread classes.

2.4 The source code of the network communication part, and carry on the simple explanation.

2.5 Choose to do: Is there a multi-threaded conflict or synchronization problem in the system? 3. Code cloud and PTA3.1 Statistics The amount of this week's work done

The weekly code statistics need to be fused into a single table.

Option: 4. Network Learning Guide (the following job content is selected) 1. Network Fundamentals

1.3 telnet cec.jmu.edu.cn 80, try to answer: what do you see from the screen? Is the content returned from the home page of cec.jmu.edu.cn? What will I return if I try to use the Get/index http/1.0 command? See the experimental Task Book topic 1.

2. Writing a TCP client program

2.1 Refer to Sockettest.java to write a simple connection to the remote server applet Client.java, you can receive and display the information sent by the server. The remote host IP and port number must first be specified on the console at startup.
