ChronoZonedDateTime minus(TemporalAmount) method in Java with Examples
minus() method of a ChronoZonedDateTime class used to returns a copy of this date-time with the specified amount subtracted to date-time.The amount is typically Period or Duration but may be any other type implementing the TemporalAmount interface.
Syntax:
default ChronoZonedDateTime minus(TemporalAmount amountTosubtract)
Parameters: This method accepts one single parameter amountTosubtract which is the amount to subtract, It should not be null.
Return value: This method returns ChronoZonedDateTime based on this date-time with the subtraction made, not null
Exception: This method throws following Exceptions:
- DateTimeException: if the subtraction cannot be made</li
- ArithmeticException: if numeric overflow occurs
Below programs illustrate the minus() method:
Program 1:
Java
// Java program to demonstrate // ChronoZonedDateTime.minus() 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]"); // subtract 10 Days to ChronoZonedDateTime ChronoZonedDateTime value = zonedlt.minus(Period.ofDays( 10 )); // print result System.out.println("ChronoZonedDateTime after" + " subtracting Days:\n " + value); } } |
Output:
ChronoZonedDateTime after subtracting Days: 2018-11-26T19:21:12.123+05:30[Asia/Calcutta]
