Refactor Commander

[iluwatar]

Description

Commander pattern has some dead code and it should be refactored. At the moment it has 4 different App classes and main functions. Each App's main function only executes the success case, but not the failure cases (dead code).

Acceptance Criteria

• 4 App classes refactored into one
• There is only one main function
• The main function executes all the success cases and the failure cases

Hello @iluwatar Do you mean to refactor all 5 App classes into one, with the main function executing both the success and failure cases?

Yes, I think that would make the example easier to use and understand.
