Cant retrieve file using relative path

I've been scouring the web for a solution to this seemingly simple problem, but I always run into FileNotFoundException. I am using Java 8 on Eclipse Oxygen and can't retrieve my txt file from either absolute path or relative path. As suggested in other SO answers I got the path to the current directory, which I suppose is where the txt file is loaded from:

Path path = FileSystems.getDefault().getPath("").toAbsolutePath();

This showed my directory as E:\eclipse-java-oxygen-R-win32\HashMap

However, when I added my txt file to that project directory (containing src,bin directories) it still couldn't find the file when I wrote: Scanner input = new Scanner(new File("free.txt"))

I even tried the absolute path: Scanner input = new Scanner(new File("E://eclipse-java-oxygen-R-win32//HashMap//free.txt"));

I included a screenshot of the location of my free.txt file below.

enter image description hereYour help would be much appreciated.

Hmm, lets try to split things up so that we know what exactly is the problem. You could also try to get a more explicit error message by printing the exact error of the File Exception. Something like this:

catch (IOException e) { 
      System.out.println("IOException caught -- "); 
      System.out.println(e.getMessage());
    }

But going further. Your line: Scanner input = new Scanner(new File("free.txt"))can be split up.

Try this:

String file_name="free.txt";
File file_input = new File(file_name);
if (!file_input.exists())
    abort("FileInput: no such source file: " + file_name);
if (!_file_input.isFile())
    abort("FileInput: can't open a directory: " + file_name);
if (!file_input.canRead())
    abort("FileInput: source file is unreadable: " + file_name);

Then run

try {
    `Scanner input = new Scanner(file_input)`
catch (FileNotFoundException e) {
        e.printStackTrace();
    }

At least this should tell you more about the error and do the debugging for you.

I don't know where your file is but I think this is what you're looking for. i have a file named test.json

String jsonString = new String(Files.readAllBytes(Paths.get(ClassLoader.getSystemResource("test.json").toURI())));
