简单的java程序代码，给段最简单的java代码 让我新手看一下

经验分享睿知

1，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 MyFirstApppublic 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！
