If you are using java.util.Date and add two different time and if it exceed beyond 24 hours, it will add 1 day to the java.util.Date. e.g. Date date1 = new Date( 0 , 0 , 0 , 20 , 59 , 59 ); System. out . println ( "Date 1: " +date1); Date date2 = new Date( 0 , 0 , 0 , 5 , 1 , 1 ); System. out . println ( "Date 2: " +date2); Date additionDate = new Date(date2. getTime ()); additionDate. setHours (date2. getHours ()+ date1. getHours ()); additionDate. setMinutes (date2. getMinutes ()+ date1. getMinutes ()); additionDate. setSeconds (date2. getSeconds ()+ date1. getSeconds ()); System. out . println ( "Addition: " +additionDate); Output: Date 1 : Sun Dec 31 20 : 59 : 59 IST 1899 Date 2 : Sun Dec 31 05 : 01 : 01 IST 1899 Addition: Mon Jan 01 0...
