Java 8 Date Time API

With Java 8, a new Date-Time API is introduced to cover the following drawbacks of old date-time API.

Thread safety
Old java.util.Date is not thread safe, thus programmers have to deal with concurrency issue while using old API.
The new date-time API is immutable and does not have setter methods.

Default Date starts from 1900, month starts from 1, and day starts from 0, so no uniformity.
