The plusDays() method of a LocalDate class in Java is used to add the number of specified day in this LocalDate and return a copy of LocalDate. For example, 2018-12-31 plus one day would result in 2019-01-01. This instance is immutable and unaffected by this method call.
Syntax:
public LocalDate plusDays(long daysToAdd)
Parameters: This method accepts a single parameter daysToAdd which represents the days to add, may be negative.
Return Value: This method returns a LocalDate based on this date with the days added, not null.
Exception: This method throws DateTimeException if the result exceeds the supported date range.
Below programs illustrate the plusDays() method:
Program 1:
// Java program to demonstrate // LocalDate.plusDays() method import java.time.*;
public class GFG {
public static void main(String[] args)
{
// create a LocalDate object
LocalDate date
= LocalDate.parse( "2018-11-13" );
// print instance
System.out.println( "LocalDate before"
+ " adding days: " + date);
// add 5 days
LocalDate returnvalue
= date.plusDays( 5 );
// print result
System.out.println( "LocalDate after "
+ " adding days: " + returnvalue);
}
} |
LocalDate before adding days: 2018-11-13 LocalDate after adding days: 2018-11-18
Program 2:
// Java program to demonstrate // LocalDate.plusDays() method import java.time.*;
public class GFG {
public static void main(String[] args)
{
// create a LocalDate object
LocalDate date
= LocalDate.parse( "2018-12-24" );
// print instance
System.out.println( "LocalDate before"
+ " adding days: " + date);
// add 15 days
LocalDate returnvalue
= date.plusDays( 15 );
// print result
System.out.println( "LocalDate after "
+ " adding days: " + returnvalue);
}
