I think unnamed package means the java file doesn't have a package. for example, like a "hello world" java program.


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

Then files with named package means they live under the package names.

For example: if a java file starts with


package com.xyz.bigapp;
public class CoolClass{
 ....
}

This "CoolClass" file must be in the folder /com/xyz/bigapp.
