java怎麼製作游戲

『壹』 怎麼用JAVA來寫一個小游戲程序

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("請輸入一個100以內的整數：");
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 (shu>num)
System.out.println("輸入的數大了，輸小點的！");
else if (shu<num)
System.out.println("輸入的數小了，輸大點的！");
else {
System.out.println("恭喜你，猜對了！");
if (i<=2)
System.out.println("你真是個天才！");
else if (i<=6)
System.out.println("還將就，你過關了！");
else if (i<=8)
System.out.println("但是你還……真笨！");
else
System.out.println("你和豬沒有兩樣了！"); break;}
}
} }

『叄』 用java做一個小游戲

import java.awt.*;
public class TowerPoint

{
return x;
