这个是一个典型的Applet,文件名应该是CarRace.java,需要图片作为车子等等,本人也是别人给的,但是还要个.html文件来运行它,代码为:

JAVA小游戏程序代码

这个是比较有名的那个烟花，不知道你有没有用：

建个工程，以Fireworks为类即可

import java.awt.*;

import java.applet.*;

import java.awt.event.*;

import javax.swing.*;

public class Fireworks extends Applet implements MouseListener,Runnable

{

int x,y;

int top,point;

/**

*对小程序进行变量和颜色的初始化。

*/

public void init()

{

x = 0;

y = 0;

//设置背景色为黑色

setBackground(Color.black);

addMouseListener(this);

}

public void paint(Graphics g)

{

}

/**

*使该程序可以作为应用程序运行。

*/

public static void main(String args[]) {

Fireworks applet = new Fireworks();

JFrame frame = new JFrame("TextAreaNew");

frame.addWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent e){

System.exit(0);

}

});

frame.getContentPane().add(

applet, BorderLayout.CENTER);

frame.setSize(800,400);

applet.init();

applet.start();

frame.setVisible(true);

}

怎么用JAVA来写一个小游戏程序

import java.util.*;

import java.io.*;

public class CaiShu{

public static void main(String[] args) throws IOException{

Random a=new Random();

int num=a.nextInt(100);

System.out.println("请输入一个100以内的整数：");

for (int i=0;i=9;i++){

BufferedReader bf=new BufferedReader(new InputStreamReader(System.in));

String str=bf.readLine();

int shu=Integer.parseInt(str);

if (shunum)

System.out.println("输入的数大了，输小点的！");

else if (shunum)

System.out.println("输入的数小了，输大点的！");

else {

System.out.println("恭喜你，猜对了！");

if (i=2)

System.out.println("你真是个天才！");

else if (i=6)

System.out.println("还将就，你过关了！");

else if (i=8)

System.out.println("但是你还……真笨！");

else

System.out.println("你和猪没有两样了！"); break;}

}

} }
