public class Configuration

extends java.lang.Object

This class contains the required parameters for the running system. There are two types of parameters:

1. Basic parameter - It's often used and important for the basic functionality of the system. It can be accessed quickly through a simple method - named according to the parametername - in its type. It can be accessed as property String as well.
2. Additional parameter - It can be accessed only as property String.

CRC
1. Retrieving and storing the configuration data.
2. Ensure easy acces to the system configuration parameters.
3. Changing parameters during the run.
