你好,陌生人,今天是我第一次写博客,内容与知识等方面都不成熟,请见谅。
如何在java里运行一个HelloWorld文本?
首先,创建一个记事本,取名为HelloWorld,后缀名为java。
然后打开记事本输入:
public class HelloWorld
{
public static void main(String[] args)
{
System.out.println("Hello World!");
}
}
括号里的Hello World!便是我们输入的内容
保存,然后win+r,输入cmd,打开命令提示符窗口
在窗口里进到HelloWorld记事本目录
并输入
javac HelloWorld.java
编译生成一个class文件
最后运行class文件就出现了Hello World!
值得一提的是运行class文件不需要加后缀名
非常感谢你能阅览完这篇文章,这无非是对我的支持和鼓励,这对我接下来的学习很有帮助句号谢谢你,陌生人!
