how do i compare current date with user input date from date picker

Question

I am trying to keep constraint on date and time. I want that if user tries to set date less than current date then it should show alert, and same thing is to be done with ti

Answer 1

Create a new Date object this way:

Date now = new Date(System.currentTimeMillis());

and use int result = now.compareTo(theOtherDate);

result will be an int < 0 if now Date is less than the theOtherDate Date, 0 if they are equal, and an int > 0 if this Date is greater.
