  • Last Updated : 14 Sep, 2021

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() method
 
import 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]
