## Goal 

Build an application for airport security using the state pattern.

-----------------------------------------------------------------------
## Implementation

1.Driver class: I call a new class from here( Let's call 
it AirportSecurityProcess)

2.AirportSecurityProcess: : This acts like a base class. This class 
reads one line at a time. It process this line, and breaks it into 
parameters. The 2 metrics are computed in this class and passes it 
to tightenOrLoosenSecurity() which is in the context class. 

3.Context : This calls the tightenOrLoosenSecurity() of the current 
state's class (by default I have assigned it to LOW_RISK). 
The state class has the conditional check to determine the 
currentState, which is returned to the context class. The context 
class then returns the currentState object to AirportSecurityProcess.


4.AirportSecurityProcess: It matches the string (e.g LOW_RISK = 1 3 5 7 9)
 with the currentState received and sends the string to Result class to 
 store in a list.
 
5.Driver : Finally the result is written to the output file.

Assuming you are in the directory containing this README:

## To clean:
ant -buildfile src/build.xml clean

-----------------------------------------------------------------------
## To compile: 
ant -buildfile src/build.xml all

-----------------------------------------------------------------------
## To run by specifying arguments from command line 
## We will use this to run your code
ant -buildfile airportSecurityState/src/build.xml run -Darg0=firstarg -Darg1=SECOND -Darg2=THIRD
