java - considering the use case of user selecting reverse time interval in android app -

the android app notify user between time interval user selects.
settings have 2 timepickers store time1 , time2

i planning store time in int format suggested following link
link --> store time in int data type in sql

following above approach while comparing current time:-

use case 1

     time1          |      time2     |   currenttime   03:00(180 int)     | 06:00(360 int) |  05:00(300 int)   time1 <= currenttime <= time2 (user receive notification) 

use case 2   (time2 < time1)

should allow user select time 2

     time1          |      time2     |   currenttime   22:00(1320 int)     |  01:00(60 int) |  23:00(1380 int)   time1 < currenttime > time2     1320 < 1380 > 60   22:00 < 23:00 < 01:00  ( respect realtime when user wants notified @ midnight)    in case user should notification if reverse time allowed.  considering user wants notification during midnight.  if((currentime > time2 && currentime <= 1439)|| (currentime > 0 && currentime <= time1)){     // notify here // 1439 == 23:59 } 

use case 3 (arises if use case 2 allowed/actually same 2 bu more time interval)

consider same case 2 time as:-        time1          |      time2       15:00(900 int)     |  10:00(600 int)   means user not want notification form morning 10:01 afternoon 14:59   user wants rest of time afternoon 15:00 next day morning 10:00 

i think best way , want know there better approach ? or easier approach ? plus should user allowed set reverse time ? if not user wont able set midnight intervals.

help appreciated.

try below helper class, think it's want.

    public class calenderutil {      public static void main(string[] args) {         string time_format = "hh:mm a";         string initialtime, finaltime, currenttime;          initialtime = "9:00 am";        finaltime = "11:00 am";        currenttime = "10:00 am";         iscurrenttimebetweengiventime(initialtime, finaltime, currenttime, time_format);          initialtime = "9:00 am";        finaltime = "12:00 pm";         currenttime = "11:00 am";         iscurrenttimebetweengiventime(initialtime, finaltime, currenttime, time_format);          initialtime = "8:00 am";        finaltime = "8:00 pm";         currenttime = "11:00 am";         iscurrenttimebetweengiventime(initialtime, finaltime, currenttime, time_format);          initialtime = "8:00 am";        finaltime = "8:00 pm";        currenttime = "11:00 pm";         iscurrenttimebetweengiventime(initialtime, finaltime, currenttime, time_format);          initialtime = "8:00 pm";        finaltime = "8:00 am";        currenttime = "11:00 am";         iscurrenttimebetweengiventime(initialtime, finaltime, currenttime, time_format);          initialtime = "8:00 pm";        finaltime = "8:00 am";        currenttime = "6:00 am";         iscurrenttimebetweengiventime(initialtime, finaltime, currenttime, time_format);     }      public static boolean iscurrenttimebetweengiventime(string initialtime, string finaltime, string currenttime, string timeformat) {         system.out.print("initialtime=" + initialtime + ", finaltime=" + finaltime + ", currenttime=" + currenttime);          boolean valid = false;         string currentdate = new simpledateformat("dd-mm-yyyy", locale.english).format(new date());         try {             //start time             date intime = new simpledateformat("dd-mm-yyyy " + timeformat, locale.english)                     .parse(currentdate + " " + initialtime);             calendar calendar1 = calendar.getinstance();             calendar1.settime(intime);              //end time             date fintime = new simpledateformat("dd-mm-yyyy " + timeformat, locale.english)                     .parse(currentdate + " " + finaltime);             calendar calendar2 = calendar.getinstance();             calendar2.settime(fintime);              date actualtime = new simpledateformat("dd-mm-yyyy " + timeformat, locale.english)                     .parse(currentdate + " " + currenttime);             calendar calendar3 = calendar.getinstance();             calendar3.settime(actualtime);              if (intime.after(fintime)) {                 calendar2.add(calendar.date, 1);                 if (actualtime.before(fintime)) {                     calendar3.add(calendar.date, 1);                 }             }              if ((calendar3.after(calendar1) || calendar3.equals(calendar1))                     && (calendar3.before(calendar2) || calendar3.equals(calendar2))) {                 valid = true;             }         } catch (parseexception e) {             e.printstacktrace();         }         system.out.println(" ==> result:" + valid);         return valid;     } } 

result:

initialtime=9:00 am, finaltime=11:00 am, currenttime=10:00 ==> result:true initialtime=9:00 am, finaltime=12:00 pm, currenttime=11:00 ==> result:true initialtime=8:00 am, finaltime=8:00 pm, currenttime=11:00 ==> result:true initialtime=8:00 am, finaltime=8:00 pm, currenttime=11:00 pm ==> result:false initialtime=8:00 pm, finaltime=8:00 am, currenttime=11:00 ==> result:false initialtime=8:00 pm, finaltime=8:00 am, currenttime=6:00 ==> result:true
