Java - txt file not able to be located

Question

I am very new to programming, my only experience this far is doing class assignments, but I want to learn how to write and read from files so I can store data.

This code is very simple and should just be printing out the contents of two txt files named "stringList" and "intlist". However, when running the code, I receive these errors:

Exception in thread "main" java.util.NoSuchElementException
    at java.util.Scanner.throwFor(Unknown Source)
    at java.util.Scanner.next(Unknown Source)
    at Main.main(Main.java:14)

When experimenting earlier, I was able to make everything work fine and the txt files were reachable to the program, but for some reason it stopped working.

Here is the main method code:

import java.io.File; // Importing file class
import java.io.FileNotFoundException; // Importing ___ to throw exception from file directory 
import java.util.*; // Importing java utilities

 public class Main{ // Class header
    public static void main(String[] args) throws FileNotFoundException { // Method header

        File stringList = new File("C:\\Users\\Administrator\\eclipse-workspace\\LearningFiles\\stringList.txt"); // Creating new File object "stringList" with stringList.txt as directory
        File intList = new File("C:\\Users\\Administrator\\eclipse-workspace\\LearningFiles\\intList.txt"); // Creating new File object "intList" with intList.txt as directory

        Scanner s = new Scanner(stringList); // Scanner reads stringList file
        Scanner s1 = new Scanner(intList); // Scanner reads intList file

        System.out.println(s.next()); // Printing first word
        System.out.println(s.next()); // Printing second word
        System.out.println(s.next()); // Printing third word
        System.out.println(s.nextLine());
        System.out.println(s.nextLine()); // Printing entire second line

        int num1 = s1.nextInt(); // Saving first number as integer variable
        int num2 = s1.nextInt(); // Saving second number as integer variable

        System.out.println(num1 + " + " + num2 + " = " + (num1+num2)); // Printing out result of integers added

    } // End of public void main
 } // End of main method

I've looked over many solutions in other threads but were unable to find any solutions that worked for me. I will list the solutions I have attempted:

1. txt files are not named "intList.txt", so the total file is not "intList.txt.txt".
2. Creating the txt files within the project folder itself.
3. The txt documents are on the same plane as the scr, not in a subfolder.
4. Including the direct folder path directory.

Help would be very appreciated!
