Hello ,
As you mentioned in other question all new Date/Time API classes are immutable and thread-safe , so why you have used "Most of the actual date related classes" in the second option instead of All ?

The statement is about java.time package that contains the new Date/Time API and that statement is taken from https://docs.oracle.com/javase/8/docs/a ... mmary.html

The classes defined here represent the principle date-time concepts, including instants, durations, dates, times, time-zones and periods. They are based on the ISO calendar system, which is the de facto world calendar following the proleptic Gregorian rules. All the classes are immutable and thread-safe.

It is talking about the main classes that represent some time or duration. They are all thread safe.

But this package also contains classes DateTimeException, which is not thread safe.

HTH,
Paul.
