        System.out.println("Directory search by path, name, extension, content and date.");
        System.out.print("\nEnter Starting directory for the search (link c:"+"\\"+"temp) : ");
        path = in.next();

        System.out.print("\nEnter the file name (like myFile or enter for all) : ");

        if((name = in.nextLine()).length() &gt; 0)
        System.out.print("\nEnter the file extenstion (like txt or enter for all) : ");
