  import java.io.*;

import java.util.*;

public class tryCountLetter {
 
    public static void main(String[]args) throws FileNotFoundException{
 
        Scanner inFile = new Scanner(new FileReader("D:\\My Documents\\Java Saves\\try.txt"));
 
    int counter = 0;
 
    String str=inFile.next();

        while(str!= "-999")

        {

        str = inFile.next();

        System.out.print(str.length());

        }

        inFile.close();

    }
 
    }

this is the error

Exception in thread "main" java.util.NoSuchElementException
at java.util.Scanner.throwFor(Scanner.java:817)
at java.util.Scanner.next(Scanner.java:1317)
at tryCountLetter.main(tryCountLetter.java:22)

i dont get it?
why does it say NoSuchElementException?

this is what's inside of the try.txt

Im a newbie -999

You can't compare strings for (in)equality like you did in line twelve. Do this
instead:

Expand|Select|Wrap|Line Numbers

while (!str.equals("-999"))

kind regards,
