Overview

toSecondsPart() is an instance method of the Duration class. It is used to obtain the number of seconds in the Duration object. The number of seconds is calculated by taking the modulus of the value returned by the toSeconds() method with the value 60. This is based on the traditional 60-second definition of a minute. This method was introduced in Java version 9.
