This article describes the Chinese chess game code implemented by Java. It is shared with you for your reference. The specific code is as follows
1. Practical purpose:
1. Application and difference between mouse click, drag and other events
2. Saving and reading of chess record files
3. Improve the rules of chess.
2. Practical content:
Chinese chess has a long history and has attracted countless people to study. Now we have made the following design and explanation of the battles of Chinese chess and the production of chess scores for your reference and learning.
1. When playing chess between machines and machines, the red side takes the lead. Drag the chess piece to the destination if it meets the rules and the squirrel is dropped.
Everyone plays chess
2. Make a chess record. After selecting the chess record menu, the game begins and the chess process is recorded.
Select the "Make Chess Record" menu
The red side won after the chess score was finished
After one side wins, the victory message dialog box pops up. After clicking OK, select the "Save Chess Record" menu to bring up the Save File dialog box.
Save chess record dialog box
3. Demonstrate the chess score. After selecting the Demonstration chess score menu, an open dialog box pops up, select the saved chess score to start the demonstration.
Demonstrate chess record dialog box
Demonstrate the chess record process (automatic and manual)

1.理解8个文件，没有太复杂的代码。
2.理解鼠标的MouseListener,MouseMotionListener两个接口的区别，五子棋的实现不需要MouseMotionListener。
3.使用LinkedList记录棋谱的方法。
