JAVA猜数字小游戏源代码

/*1、编写一个猜数字的游戏,由电脑随机产生一个100以内的整数,让用户去猜,如果用户猜的比电脑大,则输出“大了,再小点!”,反之则输出“小了,再大点!”,用户总共只能猜十次,并根据用户正确猜出答案所用的次数输出相应的信息,如:只用一次就猜对,输出“你是个天才!”,八次才猜对,输出“笨死了!”,如果十次还没有猜对,则游戏结束!*/

给段最简单的java代码 让我新手看一下

最简单的java代码肯定就是这个了,如下:

public class MyFirstApp

{

public static void main(String[] args)

{

System.out.print("Hello world");

}

}

“hello world”就是应该是所有学java的新手看的第一个代码了。如果是零基础的新手朋友们可以来我们的java实验班试听,有免费的试听课程帮助学习java必备基础知识,有助教老师为零基础的人提供个人学习方案,学习完成后有考评团进行专业测试,帮助测评学员是否适合继续学习java,15天内免费帮助来报名体验实验班的新手快速入门java,更好的学习java!
