Why am I getting a FileNotFoundException (The filename, directory name, or volume label syntax is incorrect) in Java? [closed]

问题

I am trying to create a program where it takes simple input and writes it to a file. Problem is, when it tries to open the file to write to it, I get the error: "java.io.FileNotFoundException: ‪C:\Users\bobdu\eclipse-workspace\SHIPTesting.txt (The filename, directory name, or volume label syntax is incorrect)." I even have a very simple program where I get the same error:

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.PrintWriter;

public class OutputTesting {
    public static void main(String[] args)
    {
     try
     {
        PrintWriter outputStream = new PrintWriter(new FileOutputStream("‪C:\\Users\\bobdu\\eclipse-workspace\\SHIPTesting.txt"));
        outputStream.println("Output line 1");
        outputStream.println("Output line 2");
        outputStream.close();
    }
    catch (FileNotFoundException e)
    {
        System.err.println(e.getMessage());
        e.printStackTrace(System.err);
        System.exit(0);
    }
 }

}

The file does exist for sure, I can find it in my directory. Thank you in advance for helping me.

You have a bad character in your path. When I try to paste it into eclipse, I get:

You have an extra non-printable character in your path string. It survived the copy paste as well, so i was able to reproduce your error. Here is a test:

    String yours = "‪C:\\Users\\bobdu\\eclipse-workspace\\SHIPTesting.txt";
    String retyp = "C:\\Users\\bobdu\\eclipse-workspace\\SHIPTesting.txt";

    System.out.println("yours len="+yours.length()+", retype=" + retyp.length());

The output is

yours len=49, retype=48
