What is the difference between Hash map and Property class?
i am aware Property class is used to read from a property file..But whey do we require a hash map?
In which scenario will we use Hash map? Please tell with an Example..of using both Property and hash map class?

Hash Map is a Map. That contains key Value Pairs.

I am not sure about which property class you are referring to as we have java.util.Properties class?

Properties class allows String key/value pairs to read from or write to a stream. You may have have several application specific parameters to be read at the application startup you can utilize Properties class. HashMap is a collection class which allows to use key/value pairs of objects. But HashMap is identical to Hashtable (which the Properties class itself extends from) apart from few differences. Check the API documentation of those.

As Vijitha said, Properties extends Hashtable. As such, the differences are only those between HashMap and Hashtable, and the extra methods added by Properties.
