JAVA输出文件中的文件名

逐行扫描文件，并逐行输出

        public static void main(String[] args) throws FileNotFoundException { 
                InputStream in = new FileInputStream(new File("C:\\windows")); 
                Scanner s = new Scanner(in); 
                while(s.hasNextLine()){ 
                        System.out.println(s.nextLine()); 
                } 
        }
