can't link to text file

[VinTiger]

Hi.

I can't figure out what's wrong with this program.

I have a text file in the same folder as the program, but the program gives my an error message everytime I run it that says:

java.util.NoSuchElementExeption

thankful for help

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

public final class NameNumber {

  public static void main(String... aArgs) throws FileNotFoundException {
    ReadWithScanner parser = new ReadWithScanner("mytext.txt");
    parser.processLineByLine();
    log("Done.");
  }
  
  
  public NameNumber(String mytext){
    fFile = new File(mytext);  
  }
  
    public final void processLineByLine() throws FileNotFoundException {
    Scanner scanner = new Scanner(fFile);
    try {
      
      while ( scanner.hasNextLine() ){
        processLine( scanner.nextLine() );
      }
    }
    finally {
      
      scanner.close();
    }
  }
 
  protected void processLine(String aLine){
    
    Scanner scanner = new Scanner(aLine);
    scanner.useDelimiter("=");
    if ( scanner.hasNext() ){
      String name = scanner.next();
      String value = scanner.next();
      log("Name is : " + quote(name.trim()) + ", and Value is : " + quote(value.trim()) );
    }
    else {
      log("Empty or invalid line. Unable to process.");
    }
    
    scanner.close();
  }
  
 
  private final File fFile;
  
  private static void log(Object aObject){
    System.out.println(String.valueOf(aObject));
  }
  
  private String quote(String aText){
    String QUOTE = "'";
    return QUOTE + aText + QUOTE;
  }
}

Can you copy-paste the complete error message here to see?

Here's the full error message:

D:\Java Temp>java NameNumber
Exception in thread "main" java.util.NoSuchElementException
        at java.util.Scanner.throwFor(Unknown Source)
        at java.util.Scanner.next(Unknown Source)

Can you put a catch block on processLineByLine() method and see any exceptions thrown there. You only handle the FileNotFoundException.

I got it to work:), thanks for the help

What's the issue you have there, and how did you solve it?

May be our thread starters' file content is different, with delimiters he used in.
