I am using static block, as soon as Configuration
class is loaded I will be able to get the path 
and connect to the properties file, ready to 
retrieve the desired value from properties
file using get method.

Try and Catch Block:
In this process fileInputStream object 
creation might throw an IOException, 
in order to handle this exception I 
implement try and catch block.
I also use in my DBUtilities class 
for handling SQL exceptions.
