Tryout:ZonedDateTime, Period, ChronoUnit and DateTimeFormatter .
Problem Statement
To demonstrate the working of ZonedDateTime, Period, ChronoUnit and DateTimeFormatter classes
Code in Java




Execution Result

Output:

*****ZonedDateTime******
ZonedDateTime Now: 2023-12-22T15:12:09.327+05:30[Asia/Kolkata]
ZonedDateTime Europe: 2023-12-22T11:42:09.331+02:00[Europe/Athens]

*****Period*****
Difference in days: 3

*****ChronoUnit*****
Today's date: 2023-12-22
Date after 1 month: 2024-01-22

*****DateTimeFormatter*****
2023-12-22
