我是靠谱客的博主不安樱桃，最近开发中收集的这篇文章主要介绍java课程设计猜数字游戏，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

package com.project.test;

   import java.util. *;
   public class Guess {
   private String name;
   private int score;
   public String getName()
   {
   return name;
   }
   public void setName(){
   Scanner input=new Scanner(System.in);//输入用户名
   System.out.print("请输入您的姓名:");
   name=input.next();
               }
   public int star(){
   Scanner input=new Scanner(System.in);
   int count;//猜测的次数
   int[]counts=new int[1];
   score=0;//定义成绩
   //捕获可能出现的异常
   try{
       for(int i=0;i<1;i++){
       count=0;
       int number =(int)(Math.random()*100+1);
       long startTime=System.currentTimeMillis();//开始时间
       System.out.print("请输入您猜的数:");
       int guessnum=input.nextInt();
       count++;counts[i]+=1;
       while(guessnum!= number){
           if(guessnum>100||guessnum<0)
           {
                   System.out. println("输入错误,请重新输入!");
                   return 0;
           }else if(guessnum>number){
               System.out.print("猜大了，请重新猜测:");

       }
}
   long endTime= System.currentTimeMillis();

   case 3:
   case 4:

   case 6:
   case 7:
   case 8:
   case 9:
   case 10:System.out. println("时间有点长哦!");break;
   default:System.out.println("运气太糟糕了!");break;
   }
   System.out.println("您的成绩是:"+score+"分");
}
}catch(Exception e){
       e.printStackTrace();}
       return score;
   }
