ZonedDateTime minusMinutes() method in Java with Examples

minusMinutes() method of a ZonedDateTime class used to subtract the number of minutes from this ZonedDateTime and return a copy of ZonedDateTime after subtraction.This method operates on the instant time-line, such that subtracting one minute will always be a duration of one minute earlier. This instance is immutable and unaffected by this method call.

Syntax:

public ZonedDateTime minusMinutes(long minutes)

Parameters: This method accepts a single parameter minutes which represents the minutes to subtract, It can be negative.

Return value: This method returns a ZonedDateTime based on this date-time with the minutes subtracted, not null.

Exception: This method throws DateTimeException if the result exceeds the supported date range.

Below programs illustrate the minusMinutes() method:
Program 1:

// Java program to demonstrate
// ZonedDateTime.minusMinutes() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a ZonedDateTime object
        ZonedDateTime zoneddatetime
            = ZonedDateTime.parse(
                "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]");

        // print instance
        System.out.println("ZonedDateTime before"
                           + " subtracting minutes: "
                           + zoneddatetime);

        // subtract 15 minutes
        ZonedDateTime returnvalue
            = zoneddatetime.minusMinutes(15);

        // print result
        System.out.println("ZonedDateTime after "
                           + " subtracting 15 minutes: "
                           + returnvalue);
    }
}

Output:

ZonedDateTime before subtracting minutes: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
ZonedDateTime after subtracting 15 minutes: 2018-12-06T19:06:12.123+05:30[Asia/Calcutta]

Program 2:

// Java program to demonstrate
// ZonedDateTime.minusMinutes() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a ZonedDateTime object
        ZonedDateTime zoneddatetime
            = ZonedDateTime.parse(
                "2018-10-25T23:12:31.123+02:00[Europe/Paris]");

        // print instance
        System.out.println("ZonedDateTime before"
                           + " subtracting minutes: "
                           + zoneddatetime);

        // subtract 20 minutes
        ZonedDateTime returnvalue
            = zoneddatetime.minusMinutes(20);

        // print result
        System.out.println("ZonedDateTime after "
                           + " subtracting 20 minutes: "
                           + returnvalue);
    }
}

Output:

ZonedDateTime before subtracting minutes: 2018-10-25T23:12:31.123+02:00[Europe/Paris]
ZonedDateTime after subtracting 20 minutes: 2018-10-25T22:52:31.123+02:00[Europe/Paris]
