求Java课程设计—小游戏(含源代码)

Tank——坦克大战（简洁版）源代码-------（此文档是自己在韩顺平教程总结而来）

*    功能: 1.防止敌人的坦克重叠运动

*             (决定把判断是否碰撞的函数写到EnemyTank类)

*          2.可以分关

*              2.1 (做一个开始的Panel,它是一个空的)

*              2.2 开始字体闪烁

*          3.可以在玩游戏的时候，暂停和继续

*              3.1当用户点击暂停时，子弹的速度和坦克速度设为0，并让坦克的方向

*                 不要发生变化。

*          4.可以记录玩家的成绩

*              4.1用文件流的方式（小游戏）[大游戏是用的数据库cs，bs结构,三国]

*              4.2单写一个记录类，完成对玩家的记录

*              4.3先完成保存共击毁了多少辆敌人坦克的功能

*              4.4存盘退出游戏，可以记录当时的敌人的坦克坐标，并可以恢复

*          5.java如何操作声音文件

*/

求java编写的五子棋代码，要有电脑AI的

java网络五子棋

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。

有关java AI编写得问题

0.1秒的间隔，循环就行了，这是人肉眼视觉暂留的临界值，比这大就可能看到怪物跳着移动的效果，间隔再小一点也可以，为了性能考虑尽量大

java课程设计题目及代码是什么？

java课程设计题目及代码分别是：

1、题目：计算器。设计内容是设计一个图形界面（GUI）的计算器应用程序，完成简单的算术运算。

设计要求是设计的计算器应用程序可以完成家法、减法、乘法、除法和取余运算。且有小数点、正负号、求倒数、退格和清零功能。

2、代码：

数字按钮NumberButton类如下：

import java.awt.

import java.awt.event.

import javax.swing.

public class NumberButton extends Button.

{

int number.

public NumberButton(int number).

{

super(""+number).

this.number=number.

setForeground(Color.blue).

}

public int getNumber().

{

return number;

}

}

其它java课程设计题目及代码是：

题目：华容道。编写一个按钮的子类，使用该子类创建的对象代表华容道中的人物。通过焦点事件控制人物颜色，当人物获得焦点时颜色为蓝色，当失去焦点时颜色为灰色。

通过键盘事件和鼠标事件来实现曹操、关羽等人物的移动。当人物上发生鼠标事件或键盘事件时，如果鼠标指针的位置是在人物的下方（也就是组件的下半部分）或按下键盘的“↓“键，该人物向下移动。向左、向右和向上的移动原理类似。

代码是：

String name[]={"曹操","关羽","张","刘","马","许","兵","兵","兵","兵"}.

for(int i=0;iname.length;i++).

{

person[i]=new Person(i,name[i]).

person[i].addKeyListener(this).

person[i].addMouseListener(this).

//     person[i].addFocusListener(new Person).

add(person[i]).

}

person[0].setBounds(104,54,100,100).

person[1].setBounds(104,154,100,50).

person[2].setBounds(54,154,50,100).

person[3].setBounds(204,154,50,100).

person[4].setBounds(54,54,50,100).

person[5].setBounds(204,54,50,100);

person[6].setBounds(54,254,50,50);

person[7].setBounds(204,254,50,50);

person[8].setBounds(104,204,50,50);

person[9].setBounds(154,204,50,50);
