I feel dumb asking this... File reader loop

Hello everyone! Happy Halloween Weekend!

I am trying to read 10 lines in a text file. I can read the first one, but it wont proceed past the first line! I have tried to put the command to keep going all over the place -- it never works besides reading the first line. Am I missing something too obvious here?

Code:

---



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

public class PhoneError
{
       
       
        public static void main(String[] args) throws Exception
        {
               
               
                int area = 0;
                int validArea = 0;
                int counter = 0;
               
               
        java.io.File file = new java.io.File("phone_numbers.txt");
       
       
                Scanner scan = new Scanner(file);
               
               
                /**** this gets the first line, as it should ****/

                        String number = scan.nextLine();
               
       
       
       
            if( !(number.length() == 10))
          {
                  System.out.println("not valid phone number");
          }
           
          else 
           
          {
                area = Integer.parseInt(number.substring(0, 3));
           
               
                  validArea =+ 1;
                 
                 
                 
                  if( validArea >=1 )
                  {
                         
                          System.out.println("valid area code is " + area);
                         
                          counter=+1;

                  System.out.println(counter);
               
            /****I have put the below line all over this code - nothing works to have it read the next line!  *******/
                             
                  number = scan.nextLine();
          }
                 
        }
           
 }
               
}

Code:

/****I have put the below line all over this code - nothing works to have it read the next line!  *******/
                             
                  number = scan.nextLine();

Depending on what you want to do the line shuld probably go after the if-else blcoks have finished.

You can use System.out.println("number="+number) after each of the nextLine() calls to see what you have actually read. Check this with the contents of the file.

You need to create a loop of some sort that goes until the file has no more lines.

Here is what you need:

Put your codes inside a while loop so that your program will keep executing as long as the file has more data to read.

while(scan.hasNext())
{

put your codes here

}

Well...now that Hanopac has just given you the answer lol.

Sorry for the delayed response.

Funny thing is that I put the while loop previously, but in the wrong place. I took it out to see what the error was. I honestly thought that I messed up with the scanner import or declaration.

Thanks for everything.
