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
// Java program to demonstrate// ChronoLocalDateTime.plus() methodimport 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); }} |
Output:
Original ChronoLocalDateTime: 2019-12-31T19:15:30 ChronoLocalDateTime after adding Days: 2020-01-10T19:15:30
