2. Use RecyclerView Code from Practical-9 to display Note Data.

3. Use Broadcast Receiver, Time Picker Dialog, service & AlarmManager code from Practical-7

4. Create Note class with member variables like id, title, subTitle, Description, modifiedTime, reminderTime:Long, isReminderEnable:Boolean & create membor methods like getCurrentDateTime(), getMillis(), setReminder(), isValid(), getReminderText(), saveNote(), getHour(), getMinute(), calculateReminder()
