The plus() method of a ChronoLocalDateTime interface is used to return a copy of this ChronoLocalDateTime with the specified amount added to date-time. The amount is typically Period or Duration but may be any other type implementing the TemporalAmount interface.
Syntax:
default ChronoLocalDateTime plus(TemporalAmount amountToadd)
Parameters: This method accepts one single parameter amountToadd which is the amount to add, It should not be null.
Return value: This method returns ChronoLocalDateTime based on this date-time with the addition made, not null.
Exception:
This method throws following Exceptions:
- DateTimeException – if the addition cannot be made
- ArithmeticException – if numeric overflow occurs
Below programs illustrate the plus() method:
Program 1:
// Java program to demonstrate // ChronoLocalDateTime.plus() method import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] args)
{
// Get the ChronoLocalDateTime instance
ChronoLocalDateTime ldt
= LocalDateTime
.parse( "2019-12-31T19:15:30" );
// Get the String representation of this ChronoLocalDateTime
System.out.println( "Original ChronoLocalDateTime: "
+ ldt.toString());
// add 10 Days to ChronoLocalDateTime
ChronoLocalDateTime value
= ldt.plus(Period.ofDays( 10 ));
// print result
System.out.println( "ChronoLocalDateTime after adding Days: "
+ value);
}
} |
Original ChronoLocalDateTime: 2019-12-31T19:15:30 ChronoLocalDateTime after adding Days: 2020-01-10T19:15:30
