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();


        

Answer 1

Try java.util.Calendar type.

Calendar cal=Calendar.getInstance();
cal.setTime(yourDate.getTime());
cal.set(Calendar.YEAR,n);

Answer 2

If you need add one year a any date use the object Calendar.

Calendar dateMoreOneYear = Calendar.getInstance();
dateMoreOneYear.setTime(dateOriginal);
dateMoreOneYear.add(Calendar.DAY_OF_MONTH, 365);

Answer 3

Try like this as well for a just month and year like (June 2019)

Calendar cal = Calendar.getInstance();
cal.add(Calendar.YEAR, n); //here n is no.of year you want to increase
SimpleDateFormat format1 = new SimpleDateFormat("MMM YYYY");
System.out.println(cal.getTime());

String formatted = format1.format(cal.getTime());
System.out.println(formatted);

Answer 4

Another package for doing this exists in org.apache.commons.lang3.time, DateUtils.

Date date = new Date();
date = DateUtils.addYears(date, int quantity = 1);

Answer 5

This will add 3 years to the current date and print the year.

 System.out.println(LocalDate.now().plusYears(3).getYear());

Answer 6

Try this....

String s = new SimpleDateFormat("YYYY").format(new Date(random_date_in_long)); // 
int i = Integer.parseInt(s)+n;
