Which statement is true about java.time.Duration?

A. B. C. D.C.
http://tutorials.jenkov.com/java-date-time/duration.html#accessing-the-time-of-a-durationThe correct answer is C. It defines time-based values.
The java.time.Duration class is part of the java.time package introduced in Java 8 as part of the new date/time API. It represents a duration of time in seconds and nanoseconds. It is used to represent the amount of time between two temporal objects such as LocalDateTime or Instant.
Option A is incorrect because Duration does not track time zones. Instead, it represents a duration of time independent of any time zone.
Option B is also incorrect because Duration does not preserve daylight saving time. It represents a fixed duration of time that does not change based on daylight saving time.
Option D is also incorrect because Duration is not used to represent date-based values. Instead, it is used to represent time-based values, such as the amount of time between two temporal objects.
To create an instance of Duration, you can use one of the factory methods provided by the class, such as Duration.ofSeconds(long seconds) or Duration.ofMinutes(long minutes). Once you have an instance of Duration, you can perform operations on it, such as adding or subtracting it from a temporal object.
Overall, java.time.Duration is a useful class for representing and manipulating time-based durations in Java 8 and later versions.
