从技术上讲,您可以在 main 方法中调用 string[] 吗?

main 方法的标头是

public static void main (String[] args)

你能用你想要的任何东西在技术上替换args"吗?还有,为什么参数是数组?

Could you technically replace "args" with anything you want? Also, why is the parameter an array?

推荐答案

args 只是方法中参数的名称.您可以将其重命名为您想要的任何名称.JVM 不需要知道参数是什么命名;只有 type,String[],是重要的.

args is just a name for the argument in a method. You can rename it to whatever you want. The JVM doesn't need to know what the argument is named; only the type, String[], is important.

不要破坏应用程序的起点

dont break the start point of the app

 static void main(String[] whateverYouNeed)
