Combining java.util.Dates to create a date-time

I have current have two UI components used to specify a date and a time. Both components return `java.util.Date` instances representing the calendar date and time respectively. My question is: What is the best way to combine these values to create a `java.util.Date` instance representing the date and time? **I would like to avoid dependencies on Joda or other 3rd party libraries.** My current solution looks like this (but is there a better way?): Date date = ... // Calendar date Date time = ... // Time Calendar calendarA = Calendar.getInstance(); calendarA.setTime(date); Calendar calendarB = Calendar.getInstance(); calendarB.setTime(time); calendarA.set(Calendar.HOUR_OF_DAY, calendarB.get(Calendar.HOUR_OF_DAY)); calendarA.set(Calendar.MINUTE, calendarB.get(Calendar.MINUTE)); calendarA.set(Calendar.SECOND, calendarB.get(Calendar.SECOND)); calendarA.set(Calendar.MILLISECOND, calendarB.get(Calendar.MILLISECOND)); Date result = calendarA.getTime();
That's as good as you'll get without using a proper API.
