How to compile and run the code:

Environment:

terminal

procedure:

First, open folder ./src
Second, open a terminal there
Third, compile Server.java, using the command javac Server.java
Fourth, compile Client.java, using the command javac Client.java
Fifth, run the Server.class, using command java Server
Finally, open two new terminal there and run Client.class on each of them, using command java Client

Notices:

Server communicates with clients solely by socket connection, they do not share information via joint files. Actually, you can put them in different addresses, the program will still work. But for simplicity, I just put them under the same folder. (All files except Client.java in ./src is for Server use. Client.java is independent.)
Server can continuously support rounds of game. You do not need to terminate it every time one round of game ends. However, Client will automatically close when there is a result. Start Client again each time!

Supported information(optional):

protocol:

Server ->Client:

M|string message that indicates the death of the game, client only needs to slice the ..... part E|int message that indicates indicates the result after each move U|int|int|int message that instructs client to change the chess

Client ->Server:

int|int tell which position was the chess placed Name input. a string that indicates the player has input his name
