Java – if you do not specify my class, what is the default package for my class?

Let's say I have a name called main Java file, the code is as follows:

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello world");
    }
}

It is placed in a specific package in (perhaps?) An unnamed package?

thank you

Solution

The class that is not in the named package is unnamed package Therefore, the full class name is main

Except through reflection, these classes cannot be used from named packages
