plus() method of a ChronoZonedDateTime class used to returns a copy of this date-time 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:
public ChronoZonedDateTime 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 ChronoZonedDateTime based on this date-time with the addition made, not null
Exception: This method throws the 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// ChronoZonedDateTime.plus() methodimport java.time.*;import java.time.chrono.*;import java.time.temporal.ChronoUnit;public class GFG { public static void main(String[] args) { // create a ChronoZonedDateTime object ChronoZonedDateTime zonedlt = ZonedDateTime .parse( "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); // add 10 Days to ChronoZonedDateTime ChronoZonedDateTime value = zonedlt.plus(Period.ofDays(10)); // print result System.out.println("ChronoZonedDateTime after" + " adding Days:\n " + value); }} |
Output:
ChronoZonedDateTime after adding Days: 2018-12-16T19:21:12.123+05:30[Asia/Calcutta]
