Java Date Add Days
In Java, we use the Calendar abstract class to work with the date and time. It has several useful interfaces which allow us to convert date between a specific instance in time and a set of calendar fields such as DAY, MONTH, YEAR, HOUR, etc. The Calendar class implements the Comparable interface and inherits the Object class.
Declaration of the Calendar class
In Java, we can add a single day or days to the given date or current date using Calendar class. Let's understand how we can add days to the date.
Adding Days to the given Date using Calendar class
In order to add days to the given date by using the Calendar class, we use the following steps:
Add Days to the current date using Calendar class
The steps to add days to the current date are same as the steps to add days to the given date. There is no need to define a date in this case. We get the date from the calendar here and then add days to that particular date.
Let's take an example and understand how we can add days to the current date.
Add Days to date without using Calendar class
It is very easy to add days to the date without using the Calendar class. We use the LocalDate class of the java.time package. The LocalDate class provides several methods for calculating and manipulating the current date.
Let's take an example and understand how we can use LocalDate class to calculate date in Java.
