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!
