Java import sub-sub directory

My directory structure looks like this:

folder
└───subfolder
    └───subsubfolder

I hava a Main.java in folder and Main.java uses class inside subsubfolder. Here is how I did:

import subfolder.*;
import subfolder.subsubfolder.*;

However, I got the message following when I execute javac Main.java 

$ javac -g Main.java
Main.java:23: error: cannot access Node
      Node root = new Node();
      ^
  bad class file: ./subfolder/subsubfolder/Node.class
    class file contains wrong class: subsubfolder.Node
    Please remove or make sure it appears in the correct subdirectory of the classpath.
1 error

Is my way of importing class file wrong?

Your Node class declares that it belongs to package subsubfolder, but it should belong to package subfolder.subsubfolder. Alternatively, you could move directory subfolder/subsubfolder to be a sibling of directory subfolder.

It says package subfolder

The package declaration of Node should say

package subfolder.subsubfolder;

Providing an example for clarity:

folder/
        Your source root (typically called 'src')

folder/Main.java
        class Main { ... }  (no package declaration)

folder/subfolder

folder/subfolder/subsubfolder/Node.java
        package subfolder.subsubfolder;
        public class Node { ... }

If your Main indeed lives in a package (i.e. if your situation is something like src/folder/Main.java) then you should not do

cd src/folder
javac Main.java

you should do

cd src
javac folder/Main.java
