Different Ways To Get Current Date And Time

1. Using Date Class
2. Using get() method of the Calendar class
3. Using calendar and formatter class to print the current dates in a specific format. 
4. Using java.time.LocalDate
5. Usingjava.time.LocalTime
6. Using java.time.LocalDateTime
7. Using java.time.Clock
8. Using java.sql.Date

Using Date Class

Using Date Class in this method we will explore the date and time module provided by java.util.

Parsed Date : Sat Feb 18 00:00:00 UTC 1995

Using LocalDate, LocalTime, LocalDateTime

In this method we will discuss various date and time methods provided by java.time which

• LocalDate

Current date and time: 2024-01-04T11:59:03.286975

Using System Clock

This method we will discuss the use of clock method to fetch date and time provided by java.time package.
