Code:: try { FileInputStream fileInputStream = new FileInputStream(new File("Your file path")); DataInputStream dataInputStream = new DataInputStream(fileInputStream); dataInputStream.readDouble(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }
