Cannot find symbol class

I am new to java. I am trying a simple game with three classes SimpleDotComGame, SimpleDotCom, GameHelper in three different .java files all put together in a directory dotGame. SimpleDotComGame.java has the main method. I have declared package name as

in each of these files. SimpleDotCom.java and GameHelper.java compile without any errors. But when I run SimpleDotComGame.java I get the following error:

I get the same error for SimpleDotCom class as well. Please help me with the same.

package dotGame should be package dotGame; <-- notice the ; at the end.

I have added the semicolon. The error still persists.

Hey, I got the solution. The code started working fine when I removed
from all the three classess!

But I didn't get the reason why!

There is something very peculiar. Replace the package name and use a Scanner to read through the file.
I’ll see if I can create something which will do that.

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
import javax.swing.JFileChooser;

public class ASCII_Finder
{
   private File myFile;

public static void main(String[] args)
   {
        new ASCII_Finder().readCharacters();
   }

public ASCII_Finder()
   {
       JFileChooser chooser = new JFileChooser();
       while (myFile == null)
       {
           System.out.println("Please choose a file with the dialogue.");
           if (chooser.showOpenDialog(null) == JFileChooser.APPROVE_OPTION)
           {
               myFile = chooser.getSelectedFile();
           }
       }
   }

public void readCharacters()
   {
      try
      {
          Scanner fileScan = new Scanner(myFile);
          try
          {
              int lines = 1;
              while (fileScan.hasNextLine())
              {
                  String s = fileScan.nextLine();
                  for (char c : s.toCharArray())
                  {
                      if (c < ' ' || c > '~')
                      {
                          System.out.printf(
                              "Strange character: \\u%04x which prints as %c, on line %d%n",
                              (int)c, c, lines);
                      }
                  }
                  lines++;
              }
          }
          finally
          {
             fileScan.close();
          }
      }
      catch (FileNotFoundException fnf)
      {
          fnf.printStackTrace();
      }
   }
}

Now copy the entire text of this post into a file; it’s easy enough to do it.
Give it some name like “oddCharacters.txt”.
See whether there are any characters which aren’t standard ASCII. It is possible you have a peculiar character adjacent to the keyword class causing it to be misread.
