java - Adding Years to a random date from Date class

Question

Let's say I have this:

 PrintStream out = System.out;
 Scanner in = new Scanner(System.in);
 out.print("Enter a number ... ");
 int n = in.nextInt();

I have a random date, for example, 05/06/2015 (it is not a fixed date, it is random every time). If I want to take the 'year' of the this date, and add whatever 'n' is to this year, how do i do that?

None of the methods in the Date Class are 'int'.

And to add years from an int, 'years' has to be an int as well.

Answer 1

You need to convert the Date to a Calendar.

Calendar c = Calendar.getInstance();
c.setTime(randomDate);
c.add(Calendar.YEAR, n);
newDate = c.getTime();

You can manipulate the Year (or other fields) as a Calendar, then convert it back to a Date.
