U can try java.util.Date library like this way-
int no_of_day_to_add = 1;
Date today = new Date();
Date tomorrow = new Date( today.getYear(), today.getMonth(), today.getDate() + no_of_day_to_add );
Change value of no_of_day_to_add as you want.
I have set value of no_of_day_to_add to 1 because u wanted only one day to add.
More can be found in this documentation.
