java read files from a directory line by line

Question

I have a directory with text files, those files contain a number in every line, which I have to do some calculations with. I need to read a file, read every single line in the file and then continue with another file until they all are read. I am new to Java so I was thinking of using scanner to read every line, but I haven't been able to get a file from a directory correctly.

private String Folder_path = "the path to dir";
Path kazkas = Paths.get(Folder_path);
File[] files = new File(Folder_path).listFiles();

I get to this point, but haven't found a solution how to take single file and pass it to the scanner.

My solution:

private String Folder_path = "the_path_to_fikes";
File[] files = new File(Folder_path).listFiles();
String obj = files[1].toString();
    Path path = Paths.get(obj);
    try {
        Files.lines(path).forEach(line -> {
            System.out.println(line);
        });
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
