为什么在Java中出现有关Windows文件路径的错误？

Question

I am getting a " java.util.NoSuchElementException: No line found at java.util.Scanner.nextLine(Unknown Source) at parker.MovieLibrary.<init>(MovieLibrary.java:22) at parker.SelectorUserInput.main(SelectorUserInput.java:10) " error when trying to open a file.

Below is the code of the MovieLibrary constructor that is giving me trouble:

    public MovieLibrary() {

        String FILENAME = "\\Users\\FirstName LastName\\Desktop\\JavaIndividualAssignment\\FinalMovieList1.txt";
        Scanner input = new Scanner(FILENAME);
        File file = new File(input.nextLine());
        String[] split;
        try {
            File file1 = new File(input.nextLine());
            input = new Scanner(file1);
            while (input.hasNextLine()) {
                String line = input.nextLine();
                //code to add movies to an ArrayList
            }
                //input.close();
        }
        catch (Exception ex) {
                ex.printStackTrace();
        }
        finally{
            if (input != null){
                input.close();
            }
        }
    }   
}

I tired all of the suggestions listed here: Java File Path Windows/Linux , but none of them worked.I got the same error each time. I replaced the backslashes with single forward slashes, tried using the Path object, nothing changed the error.

Is this an issue with my file path? I used the same file-opening code on a different computer and it found the file just fine.

Answer 1

You are constructing a Scanner object of the filename string (\\Users etc). Pretty sure you want to create a File object of the string and a Scanner object of that File object.

Answer 2

String FILENAME = "C:\\Users\\FirstName LastName\\Desktop\\JavaIndividualAssignment\\FinalMovieList1.txt";
 Scanner input=null;
    File file = new File(FILENAME);
    String[] split;
    try {

         input = new Scanner(file);
        while (input.hasNextLine()) {
            String line = input.nextLine();
            //code to add movies to an ArrayList
        }
            //input.close();
    }
    catch (Exception ex) {
            ex.printStackTrace();
    }
    finally{
        if (input != null){
            input.close();
        }

}
