一、实践目的

1．掌握Java常用基础类API。

2．掌握输入输出流常用类API。

3．掌握Java异常处理。

二、实践要求

利用Java常用基础类API、输入输出流常用类API、Java异常处理等完成所选项目的程序设计。

三、项目需求

所选项目名称：五子棋游戏

现在各大软件公司都有自己的、各种的程序，但是这些公司都有自己的版权，我们也不可能得到这些源代码！而且这些公司的程序也相当复杂，仅从日常应用方面来说，对于初学java的我们也无法理解，就需要我们开发一个简单易懂的五子棋游戏程序。

四、核心算法详细设计     

本程序实现的是一单机双人对战五子棋游戏

本程序由五个java源程序文件组成，Game.java、GameFrame.java、GamePanel.java、 ChessMan.java、Player.java

Game.java
import javax.swing.*;

public class Game {

public static void main(String[] args) {

GameFrame GFrame=new GameFrame();
GFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
GFrame.setVisible(true);
}

}

GameFrame.java
import java.awt.*;
import javax.swing.*;

class GameFrame extends JFrame {

private static final int Width=570;
private static final int Height=470;

GameFrame(){
setTitle("五子棋游戏");
CenteredFrame();
setSize(Width,Height); 
GamePanel Gpanel=new GamePanel();
add(Gpanel); 
}

void CenteredFrame(){
Toolkit kit=Toolkit.getDefaultToolkit();
Dimension screenSize=kit.getScreenSize();
int screenHeight=screenSize.height;
int screenWidth=screenSize.width;

int Xposition=(screenWidth-Width)/2;
int Yposition=(screenHeight-Height)/2;
setLocation(Xposition,Yposition);
}
}

五、程序运行结果

六 、心得体会

过这次的结对实验，我从书本上学习到的理论知识用到了实践上，从而进一步巩固和丰富了我所学过的知识，让我更深层次地认识到Java及其强大的功能。同时，做这门课程设计也进一步加强了我的动手能力与合作能力。

赵存存代码写的很清楚，我们交流的非常愉快。
