Why do I get an "java.nio.file.NoSuchFileException" error even though the file exists?

Question

I'm getting the error Exception in thread "main" java.nio.file.NoSuchFileException but I'm sure the file exists at the given location C:\\Users\\Admin\\Desktop\\Java.txt".

Why do I still get this error?

import java.io.IOException;
import java.nio.file.Paths;
import java.util.Scanner;

public class ReadData {
  public static void main(String[] args) throws IOException {
        
    Scanner file = new Scanner(Paths.get("C:\\Users\\Admin\\Desktop\\Java.txt", "UTF-8"));
    int int_value;
    while ((file.hasNextInt())) {
        int_value = file.nextInt();
        System.out.println("Data:" + int_value);
    }

    file.close();
  }
}

"no such file" error suggests that the file you're trying to use does not exist. Do you think it does? — Joni, Jul 05 '20 at 02:28
It occurs both VSC and Elipse IDE, And I just downloaded it yesterday. How to configed it — Nagai Kei, Jul 05 '20 at 02:34
Umm ... look in the file system to see if there is a file at "C:\\Users\\Admin\\Desktop\\Java.txt". If it doesn't exist **at that location** ... that's why your application cannot find it! Possible solutions: 1) create the file, or 2) correct the path in your program. — Stephen C, Jul 05 '20 at 02:44

Well remove the "UTF-8" if you dont have a file named "UTF-8": Scanner file =new Scanner(Paths.get("C:\\Users\\Admin\\Desktop\\Java.txt")); — kai, Jul 05 '20 at 09:37
Paths.get("C:\\Users\\Admin\\Desktop\\Java.txt", "UTF-8") means a file with path "C:\\Users\\Admin\\Desktop\\Java.txt"\\UTF-8". Is that what you wanted? — armagedescu, Jul 05 '20 at 17:39

I believe your issue is with your Paths.get() method:

Scanner file = new Scanner(Paths.get("C:\\Users\\Admin\\Desktop\\Java.txt", "UTF-8"));

The closing parentheses for the Paths.get() method is in the wrong place. What you are actually supplying to the Scanner object (or what the get() method interprets it to be) is a path like this:

"C:\Users\Admin\Desktop\Java.txt\UTF-8"

That particular path obviously can not be found. It should be:

Scanner file = new Scanner(Paths.get("C:\\Users\\Admin\\Desktop\\Java.txt"), "UTF-8");

You may want to also consider utilizing the Try With Resources mechanism. It will auto-close the file reader:

try (Scanner file = new Scanner(Paths.get("C:\\Users\\Admin\\Desktop\\Java.txt"), "UTF-8")) {
    int int_value;
    while ((file.hasNextInt())) {
        int_value = file.nextInt();
        System.out.println("Data:" + int_value);
    }
}
catch (IOException ex) {
    ex.printStackTrace();
}

just keep the text file in your project folder and simply change the code like below

Scanner file=new Scanner(new File("Java.txt")); hope it will solve your issue
