这个曾是我的毕业设计，是得了A的。保证能用 下面的源代码分为4个文件；chessClient.java:客户端主程序。 chessInterface.java:客户端的界面。 chessPad.java:棋盘的绘制。 chessServer.java:服务器端。 可同时容纳50个人同时在线下棋，聊天。 没有加上详细注释，不过绝对可以运行，j2sdk1.4下通过。 /*********************************************************************************************1.chessClient.java **********************************************************************************************/import java.awt.*;
