如何在 NetBeans IDE 中重命名我的主要 class？

Question

I am using NetBeans IDE and have created a new project. The new project includes a Main.java.

Is it necessary to have it named Main.java, or can I rename the Main.java into another name? If so, how can I do this? When I try to right-click Main.java, there is no rename option. I thought it was possible.

Answer 1

There should be a menu item called

Refactor --> Rename

Link from NetBeans Wiki

Your name can be anything, as long as you have a

public static void main(String[] args) 

in it (This is only if you want this class to be the entry point when you run your application).

Answer 2

You can call the file <whatever you like>.java , but the name of the class in that file must match the new name you give to the file.

So if you rename the file to MyCoolClass.java, you also have to change the class from public class Main to public class MyCoolClass .

Answer 3

you can even have the simpler way,click on the file_name.java in the Projects panel,wait for a sec and click one more time (just as you rename any other folder/file).It will allow you to replace the new name and then it will popup a window asking whether you want to refactor or not...

Answer 4

you got to use the refractor, as it is the safest way to do such actions
