java.io.FileNotFoundException - file DOES exist in directory

I keep receiving the same error whilst trying to read a file. The file DOES exist in the directory, what am I doing wrong?

package test;

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;

public class MenuSample{

    public static void main(String[] args) {

        File f = new File("C:/Users/Joe/Documents/workspace/ArtificialLifeFX/res/latest.txt");

        Scanner scanner = null;
        try {
            scanner = new Scanner(f);
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        scanner.useDelimiter("\r\n");
    }
}

I get the following error:

java.io.FileNotFoundException: C:\Users\Joe\Documents\workspace\ArtificialLifeFX\res\latest.txt (The system cannot find the file specified)
    at java.io.FileInputStream.open(Native Method)
    at java.io.FileInputStream.<init>(Unknown Source)
    at java.util.Scanner.<init>(Unknown Source)
    at test.MenuSample.main(MenuSample.java:16)
Exception in thread "main" java.lang.NullPointerException
    at test.MenuSample.main(MenuSample.java:21)

Forgive me if I'm being naive, I'm new to java. I'm running Eclipse Luna on Windows 7.

It is possible that the file exists but eclipse is not seeing it. Try to refresh the project in project explorer and make sure that this file appears under project explorer. Since the file you are referencing is under workspace folder than it should appear in the project explorer.

Believe the JVM when it tells you such things. There's no sense insisting you're correct; you can't win that argument. You need to figure out what you've done wrong.

My suggestion? Try this:

    File f = new File("C:\\Users\\Joe\\Documents\\workspace\\ArtificialLifeFX\\res\\latest.txt");

On my Windows 7 machine it would be:

    File f = new File("C:\\Users\\Joe\\My Documents\\workspace\\ArtificialLifeFX\\res\\latest.txt");

Check your path to make sure it's absolutely spot on.
