assignment to validate UK postcodes

Postcode Validator

Total number of days to implement the project: 3 days (with brakes in between and research work involved)

This program is built on Java 8 and is dependant on Stream API. It also requires maven 3.3.9+

Reason to choose Java:

I was recently working on Java platform and have more number of years of experience (4 years) compare to Python. Well aware of standard Java APIs.

Other benefits include:

• It is flexible, portable, widely used, can run on remote machines
• Latest Java 8 uses lambda functions and has capability of using filters

Running the Project

The code can be compiled and executed using maven via commandline or latest java supported IDE.

Following line is used to compile the code (using command-line):

$ cd PostCode 
$ mvn clean install

To run the tests:

$ mvn test

To run the main program to read csv file and create respective valid/invalid files:

$ mvn exec:java

You would need to enter number '1' or '2' to perform the task

Note:

$ src/main/resources/import_data.csv
or
$ src/test/resources/import_data.csv
