Task: Refactor HelloWorld to use JSAP

In the HelloWorld example you wrote for Task 3, you wrote custom logic to parse the command line arguments.

JSAP is a very good open source library that does command line argument parsing. Download JSAP and use it to parse command line arguments in the HelloWorld exercise.

While refactoring code, try and use refactoring support in your IDE.

Describe what you did, any problems that you may have faced and how you overcame them, in a blog post.
