Method for Reading the file:

   static void readDetails(String fileName) throws IOException {

       DataInputStream data = new DataInputStream(new FileInputStream(fileName));

       try {

           while (true) {

               int patientID = data.readInt();

               String patientName = data.readUTF();

               float billAmount = data.readFloat();

               if (billAmount > 1_00_000)

                   System.out.printf("Patent Name - %s%n" +

                           "Patient ID - %d%n" +

                           "Bill Amount - %f", patientName, patientID, billAmount);

           }

       } catch (EOFException e) {

           System.out.println("Finished reading file");

       }

       data.close( );

   }
