JAVA 编写hello world

要在Java中编写一个Hello World程序,你可以使用以下代码:
```java
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}
```
在这个程序中,我们定义了一个名为HelloWorld的公共类,具有一个名为main的公共静态方法。在main方法中,我们使用System.out.println语句打印出了"Hello, World!"的消息。
如果你想要使用快捷键来输入public static void main(String[] args) {},你可以使用psvm来代替。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
