Hi Venkata krishna, 

Can you please let us know, how is your input going to be like ? 

Is it going to be a 3 combination strings like : 

Input --1

Years : 4 Months : 6  Days : 7

Expected Output : will be updating the months string to 6 and days string to 0 ? 

Input --2

Years : 4 Months : 6  Days : 17

Expected Output : will be updating the months string to 7 and days string to 0 ? 

Is this what you want ? 

Please let me know if my understanding is correct.

We can surely achieve this using an activity, where we can check the days count by parsing the days string and then set the days to 0, incrementing or decrementing the months using a condition on days count and then evaluate the year too (if incase the month is already 12 and the days is > 15, year has to be increased).

Thanks,

Sai

 Please see the attached, that has the logic for the java activity I have tried out, it gives the expected output.

Thanks,

Sai

=====Logic====

int days = Integer.parseInt(tools.getParamValue("days"));

int months =  Integer.parseInt(tools.getParamValue("months"));

int years =  Integer.parseInt(tools.getParamValue("years"));

if(days > 15){

  if(months == 11){ // if month is 11, then we have to get months value back to 1 and increment years.

    months = 1;

    years++;

  }else {           // Any other month other than 12 will just increase month value by 1.

    months++;

  }

}

days = 0; // under any circumstances, we have to update days of to 0.

//oLog.error("Days : "+days + " Months :"+months + " Years : "+years); --Test print

// Expected Output.

if(months == 0){

  oLog.error(years + " year(s)"); 

}else{

  oLog.error(years + " year(s) " + months + "month(s)");

}
