Trouble creating a folder then creating files within the folder

Hi I'm having a problem creating a folder in which every file I create in my for each loop will be placed. It is a basic problem but I can't seem to see it, any help would be much appreciated!

Scanner inputScan = new Scanner(System.in);
    System.out.println("Enter location for output folder to be built..");
    String filePath=inputScan.next();
    inputScan.close();

    File dir = new File(filePath+"subnet_output");
    dir.mkdir();


    for(String myAddr: addr){
        String myFileName = myAddr.replaceAll("/", "-");

        File file = new File(dir+myFileName+".txt");
        PrintWriter writer = new PrintWriter(file, "UTF-8");

You are missing "/" while creating file inside folder:

File file = new File(dir+myFileName+".txt");

Replace with:

File file = new File(dir+File.pathSeparator+myFileName+".txt");

Try PrintWriter.append(...) and PrintWriter.flush() for actually writing into that file you want to create.
