J2ME中的小游戏 ！替换！System.in

[apple_box]

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Random;


public class wenjian {

/**
* @param args
*/
public static void main(String[] args) throws IOException {

int random = new Random().nextInt(100);
System.out.println("欢迎参与猜字游戏");
System.out.println("请输入1-100内你猜的数字");
for (int i = 1; i <= 100; i++) {
BufferedReader buff = new BufferedReader(new InputStreamReader( System.in));
String bufStr = buff.readLine();
int buffReader = Integer.parseInt(bufStr);
if (buffReader > random) {
System.out.println("你输入的数太大哦！");
}
if (buffReader < random){
System.out.println("你输入的数太小哦！");
}
if (buffReader == random) {
System.out.println("恭喜你回答正确！");
random = new Random().nextInt(100);
System.out.println("继续游戏请重新输入");
buff = new BufferedReader(new InputStreamReader(System.in));
}

}
}
}

提示：在J2ME中调试 错误 System.in 无法解析``
求换为J2ME中专用的语句代替```

你写的这是j2se程序，在j2se环境下运行

j2me下的程序差别很多，另看书

对啊``我是只学了``J2SE
是想把它改成J2ME中的``最终是运用在手机中的`.jar小游戏`。
游戏很简单```就是不会`J2ME
望高手 帮忙``

Graphics g;
int a,b//屏幕中初始位置
g.drawString("欢迎参与猜字游戏",a,b,Graphics.TOP| Graphics.LEFT);

貌似ＪＤＫ１.５简化了Ｉ／Ｏ
这个程序可以更简化
貌似这个程序是ＪＡＶＡ咖啡馆里面的样例，去了try{} catch语句

我运行了``可是提示 :No midlets defined in JAD File. Continue?
我继续了```可是模拟器 显示不出来东西``。。
怎么回事啊？

谢谢 过了！~

成功`
