Given a Date dt you have several possibilities:
Solution 1: You can use the Calendar class for that:
Date dt = new Date();
Calendar c = Calendar.getInstance();
c.setTime(dt);
c.add(Calendar.DATE, 1);
dt = c.getTime();
Solution 2: You should seriously consider using the Joda-Time library, because of the various shortcomings of the Date class. With Joda-Time you can do the following:
Date dt = new Date();
DateTime dtOrg = new DateTime(dt);
DateTime dtPlusOne = dtOrg.plusDays(1);
Solution 3: With Java 8 you can also use the new JSR 310 API (which is inspired by Joda-Time):
Date dt = new Date();
LocalDateTime.from(dt.toInstant()).plusDays(1);
Solution 4: With org.apache.commons.lang3.time.DateUtils you can do:
Date dt = new Date();
dt = DateUtils.addDays(dt, 1)

Date today = new Date();
Date tomorrow = new Date(today.getTime() + (1000 * 60 * 60 * 24));
Date has a constructor using the milliseconds since the UNIX-epoch. the getTime()-method gives you that value. So adding the milliseconds for a day, does the trick. If you want to do such manipulations regularly I recommend to define constants for the values.
Important hint: That is not correct in all cases. Read the WARNING comment, below.

October 16, 2024Creating a while loop calendar.
I'd start with making an enum beginning with Sunday (1) ending with Saturday (7). Given a start day (E.g Wednesday = 4) iterate the rest of the week (5, 6, 7), for (int i=0; i< (7 - 4) { WEEKS.valueOf(i); } That gives us 3 days on our calender, and leaving us to start on Sunday. If the user entered 30 total days, we have 27 days left beginning on Sunday. You should iterate 27 times, starting from 1-7 until the number is no longer divisble by 7, leaving the ending week.

r/learnjavascript on Reddit: Looking for help on Java Script that adds 50 days to current date
October 16, 2024 -
Hello All,
I was tasked at work to develop a dynamic stamp to use on our Kofax Power PDF documents. So i made the stamp form and now I am to the point where i need some help. Part of the STAMP needs to display the date that is 50 calendar days from the current date. I can get to where the current date is displayed.
event.value = (new Date()).toString();
AFDate_FormatEx("mmm/dd/yyyy");
This is the code as it appears in my JavaScript editor, within Power PDF. That code displays:
Oct/16/2024
What I need it to display is the date that is 50 days in the future. Ive tried using ChatGPT and it spits out the code but it doesn't work when I paste it. What am I missing? Any help would be appreciated.
Thanks!

With details: const now = new Date().getTime(); const numDays = 50 const addition = numDays*24*60*60*1000; console.log(new Date(now + addition)); Abbreviated: const numDays = 50; const futureDate = new Date(new Date().getTime() + numDays*24*60*60*1000); console.log(futureDate);
