为 Java 程序创建一个文件夹，然后使用 VS Code 打开该文件夹。然后在 VS Code 中创建一个新文件并以名称保存Hello.java。当您打开该文件时，Java 语言服务器会自动开始加载，您应该会在状态栏右侧看到一个带有加载图标的语言状态项，显示语言状态正忙。加载完成后，您可以将鼠标悬停在语言状态项上，发现加载过程...
1.public class:能生成class文件并且能运行JAVA文件,class文件是java编译后产生的文件能被解释,(java文件的运行需要两个步骤第一步为编译第二步为解释) 2.public static void main:是Java程序的入口地址,Java虚拟机运行程序的时候首先找到main方法,和c语言中的main函数是一样的。 3.public:表示这个程序访问的权限,...
这是一个入门的 Java 练习题。这个题目中,你的任务是使用 Java 中的System.out.println函数打印Hello World到控制台输出(标准输出)。 你可以在代码中看到一个叫做HelloWorld的类,在这个类中定义了一个叫做Main的静态方法。这个就是你整个程序的入口了,你需要在这个方法中编写代码实现打印。
