Using Java for Date, Time, Duration

 We have been using the below packages and the classes for Data Time for long time. But after Java 8 release there is big relief for developers and they can do date, time manipulations with lesser code. 

We will compare them. 

java.util.* - Old date, time package

java.sql.* - Implements the classes from above package java.util.*

java.time.* - The new Java 8 package with lot of convenient features.

joda time api - Which was fulfilling the gaps in java.util packages.
