• minusMinutes() method is available in java.time package.
• minusMinutes() method is used to subtract the given duration in minutes from this Duration and returns the Duration.
• minusMinutes() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• minusMinutes() method may throw an exception at the time of performing subtraction.
  ArithmeticException – This exception may throw when the calculated result value exceeds the limit.

Syntax:

    public Duration minusMinutes(long min_val);

Parameter(s):

• long min_val – represents the minutes to be subtracted from this Duration.

Return value:

The return type of this method is Duration, it returns the Duration that holds the value subtracted the given minutes from this Duration.

Example:

// Java program to demonstrate the example 
// of minusMinutes(long min_val) method of Duration

import java.time.*;

public class MinusMinutesOfDuration {
    public static void main(String args[]) {
        long minutes = 10;

        // Instantiates two Duration objects
        Duration du1 = Duration.ofMinutes(40);
        Duration du2 = Duration.parse("P2DT2H20M");

        // Display du1, du2 
        System.out.println("du1: " + du1);
        System.out.println("du2: " + du2);
        System.out.println("minutes to substract:" + minutes);

        System.out.println();

        // subtracts the given duration
        // in minutes from this Duration du1 
        // and returns the Duration i.e. here we 
        // are substracting the given 10 minutes
        // from this du1 that holds the value of 40 
        // minutes
        Duration minus_val = du1.minusMinutes(minutes);

        // Display minus_val
        System.out.println("du1.minusMinutes(minutes): " + minus_val);

        // subtracts the given duration
        // in minutes from this Duration du2 
        // and returns the Duration i.e. here we 
        // are substracting the given 10 minutes
        // from this du2 that holds the value of 
        // 2D:2H:20M
        minus_val = du2.minusMinutes(minutes);

        // Display minus_val
        System.out.println("du2.minusMinutes(minutes): " + minus_val);
    }
}

Output

du1: PT40M
du2: PT50H20M
minutes to substract:10

du1.minusMinutes(minutes): PT30M
du2.minusMinutes(minutes): PT50H10M
