扫描仪无法从文件中读取文本

Question

I am having an issue where I am trying to use Scanner to add elements to an arraylist from a text file. I have looked over my code what feels like a thousand times and I can't seem to find the issue.

Scanner scan = new Scanner(new File(fileNameSub)); //scanner object that locates the file
    scan.useDelimiter("\\n"); //delimiter for scanner

        ArrayList<String> fileList = new ArrayList<>(); //create arraylist to hold txt file contents                

        while(scan.hasNextLine()) {
            fileList.add(scan.nextLine());
        } // while loop that adds the contents so the arraylist

Please let me know if you see any errors that could be causing the issue.

Thanks in advance.

Answer 1

Remove scan.useDelimiter("\\\\n" ); and try again, or better use NIO2

List<String>lines = Files.readLines(Paths.get(file), StandardCharsets.UTF_8);
