Question

Good Day . I just wanna ask about adding days in a given date. I have a jtexfield (txtStart) and another jtexfield(txtExpiry). I need to display in txtExpiry the date after 102

Once you have the correct format, you could use JodaTime. You could parse the String value directly using JodaTime, but since you've already done that, I've not bothered...

Date date = ...;
DateTime dt = new DateTime(date);
dt = dt.plusDays(102);
date = dt.toDate();
