Duration Class abs() method

• abs() method is available in java.time package.
• abs() method is used to clone this Duration but available with positive duration value instead of a negative duration.
• abs() 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.
• abs() method may throw an exception at the time of returning the absolute value of this Duration.
  ArithmeticException: This exception may throw when the calculated result exceeds.

Syntax:

    public Duration abs();

Parameter(s):

• None

Return value:

The return type of this method is Duration, it returns this Duration but available with positive absolute duration values.

Example:

// Java program to demonstrate the example 
// of Duration abs() method of Duration

import java.time.*;
import java.time.temporal.*;

public class AbsOfDuration {
    public static void main(String args[]) {
        // Instantiates two Duration objects    
        Duration du1 = Duration.between(LocalTime.MAX, LocalTime.MIN);
        Duration du2 = Duration.ofHours(-2);

        // Here, we are representing absolute
        // values of du1 and du2 by using abs() method
        Duration du1_abs = du1.abs();
        Duration du2_abs = du2.abs();

        // gets the value of the given unit for
        // du1 and du1_abs
        long du1_sec = du1.get(ChronoUnit.SECONDS);
        long du1_sec_abs = du1_abs.get(ChronoUnit.SECONDS);

        // Display du1 and du1_abs
        System.out.println("du1: " + du1_sec);
        System.out.println("du1.abs(): " + du1_sec_abs);

        System.out.println();

        // Display du2 and du2_abs
        System.out.println("du2: " + du2);
        System.out.println("du2.abs(): " + du2_abs);
    }
}

Output

du1: -86400
du1.abs(): 86399

du2: PT-2H
du2.abs(): PT2H
