Java, trying to compile, get following error message, what does this mean?

Alright so when I try to compile this in java, I get the following error message

error: Class names, 'TokenTest', are only accepted if annotation processing is explicitly requested 1 error

What does this mean and how can I fix it? I've tried numerous things but cant understand what it is referring to. Thanks for your help! Does this mean I need to change the name so it isn't TokenTest?

 import java.io.*;

  import java.util.*;

  class TokenTest {

     public static void main (String[] args) {
        TokenTest tt = new TokenTest();
        tt.dbTest();
     }
     void dbTest() {

        DataInputStream dis = null;
        String dbRecord = null;

        try {

           File f = new File("sales.info");
           FileInputStream fis = new FileInputStream(f);
           BufferedInputStream bis = new BufferedInputStream(fis);
           dis = new DataInputStream(bis);

           // read the first record of the database
           while ( (dbRecord = dis.readLine()) != null) {

              StringTokenizer st = new StringTokenizer(dbRecord, ",");
              String fname = st.nextToken();
              String lname = st.nextToken();
              String city  = st.nextToken();
              String state = st.nextToken();

              System.out.println("First Name:  " + fname);
              System.out.println("Last Name:   " + lname);
              System.out.println("City:        " + city);
              System.out.println("State:       " + state + "\n");
           }
        } catch (IOException e) {
           // catch io errors from FileInputStream or readLine()
           System.out.println("Uh oh, got an IOException error!" + e.getMessage());

        } finally {
           // if the file opened okay, make sure we close it
           if (dis != null) {
              try {
                 dis.close();
              } catch (IOException ioe) {
              }
           }//  end if
        }// end finally
     } // end dbTest
  } // end class

From this link about common problems when compiling Java:

Class names, 'HelloWorldApp', are only accepted if annotation processing is explicitly requested

If you receive this error, you forgot to include the .java suffix when compiling the program. Remember, the command is javac HelloWorldApp.java not javac HelloWorldApp.

After fixing the error, you would get a warning about the use of a deprecated method in the following line:

while ((dbRecord = dis.readLine()) != null) {

This is because DataInputStream#readLine is deprecated. See the class Javadoc page to know why it is deprecated and which API to use instead.
