We will also take a look at the core classes in the Java8 time class library, such as LocalDate, LocalTime, LocalDateTime, ZonedDateTime, Period, Duration and their APIs. 2. The problem of thread safety of the old time API (before Java 8)-Date and Calendar classes are not thread-safe, making it difficult for developers to debug concurrency problems of these APIs and need to write additional code to deal with them.
