A library app sets a book's return reminder for the day after the issue date. Read a date as day, month and year and print the next day's date in the same form.
Months have their usual lengths, and February has 29 days in a leap year (divisible by 4 and not by 100, or divisible by 400). If the date read does not exist, such as 31 4 2024 or 29 2 2023, print Invalid date.
day month year, or Invalid date.Example 1
Input
28 2 2024
Output
29 2 2024
2024 is a leap year, so the next day is 29 February.
Example 2
Input
31 12 2023
Output
1 1 2024
The last day of the year rolls over to a new year.
Example 3
Input
31 4 2024
Output
Invalid date
April has only 30 days.
Try the problem first. Open one hint at a time.
First work out how many days the month has, using a switch on the month. Use 0 days for an invalid month.
The date is invalid if the month is invalid or the day is less than 1 or more than the month's days.
For a valid date: if the day is not the last day of the month, just add 1 to the day. Otherwise move to day 1 of the next month, and from December move to January of the next year.
Write your Java code, run it on the examples and submit it to hidden tests.
