why is my method using a Tokenizer hanging up on the second token?

You're not prompting in the same sequence you're expecting the response in. You only ask for the number and then try to read more than one input (which will block, waiting for more input)

because you (attempt to) read a new line each time you call token.

you need to read all three from one line:

         static int[] token()throws IOException
          {
          BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

          int tokens;
          StringTokenizer reader;

          reader = new StringTokenizer(in.readLine(), "-");
         
          return new int[] { Integer.parseInt(reader.nextToken()), Integer.parseInt(reader.nextToken()), Integer.parseInt(reader.nextToken()) };

          }// method token

You need something more like this:


import java.io.*;
import java.util.*;

class Phone {

      public static void main(String[] args) throws IOException {
            System.out.print("Please enter phone number:   ");
            String[] parts = getNumberParts();
            System.out.println(parts[0] + " is the area code");
            System.out.println(parts[1] + " is the exchange");
            System.out.println(parts[2] + " is the extension");

      }
      //method main

      /**

       *
       * @return                  The numberParts value
       * @exception  IOException  Description of the Exception
       */
      static String[] getNumberParts() throws IOException {
            BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
            return in.readLine().split("-");
      }

}
// class Phone

     {
          int area, exchange, extension;
          String reader;

          System.out.print("Please enter phone number:   ");
          int[] phone = token();
          area=phone[0];
          System.out.println(area+ " is the area code");
          exchange=phone[1];
          System.out.println(exchange+ " is the exchange");
          extension=phone[2];
          System.out.println(extension+ " is the extension");

     } //method main
//*********************************************************************

         static int[] token()throws IOException
          {
          BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

          int tokens;
          StringTokenizer reader;

          reader = new StringTokenizer(in.readLine(), "-");
         
          return new int[] { Integer.parseInt(reader.nextToken()), Integer.parseInt(reader.nextToken()), Integer.parseInt(reader.nextToken()) };

          }// method token
}

>>int area, exchange, extension;

You variables look plausible but really phone numbers are Strings, apart from the very rare occasions when arithmetic needs to be done on them

still doesnt work??????  compiles but the output is garbage.

also, Im not familiar with int [] ....what does this stand for?

      public static void main(String[] args)throws IOException

            int area, exchange, extension;
            String reader;

            System.out.print("Please enter phone number:   ");

            area=token();
            System.out.println(area+ " is the area code");
            System.out.flush();
            exchange=token();
            System.out.println(exchange+ " is the exchange");
            System.out.flush();
            extension=token();
            System.out.println(extension+ " is the extension");

      } //method main

            reader = new StringTokenizer(in.readLine(),"-");
            
            return new int[]{ Integer.parseInt(reader.nextToken()), Integer.parseInt(reader.nextToken()), Integer.parseInt(reader.nextToken()) };


            }// method token


} // class Phone

            

> with int [] ....what does this stand for?

an array of int's, 3 in this case

you are my new best friend

I was very close to lighting myself on fire

Glad I could help :)

hedge243, can you tell me why you ignored my (correct) answer to the question?
