For an HTML text field, you can to supply a string representation of a date to the element’s value attribute. To get the current date, call java.util.Calendar.getInstance() and use the resulting Calendar’s getTime() method, which returns a java.util.Date object, to determine regDate. Increase the Calendar’s year with add(Calendar.YEAR, 1) and get another Date for next year’s date.

value

java.util.Calendar.getInstance()

Calendar

getTime()

java.util.Date

Calendar

add(Calendar.YEAR, 1)

Date

Edit: I had broken code before, but this should work.

<%@ page import = "java.util.Calendar" %>
<%@ page import = "java.util.Date" %>
<%! public Calendar cal = Calendar.getInstance(); %>


And later in the page:

<input type="text" name="regDate" value=<%= """+cal.getTime()+""" %> />
<% cal.add(Calendar.YEAR, 1); %>
<input type="text" name="endDate" value=<%= """+cal.getTime()+""" %> />
