Program Plan Intro

Program Plan:

• Open the CommandWords class.

• Modify the showAll() method to create a new String variable called commandWordString.

• Print out the final commandWordString variable along with a label of "Commands:".

• Open the Parser class.

• Add a new method called showCommands() that calls the showAll() method of the CommandWords class.

• Open the Game class.

• Modify the printHelp() method to call the showCommands() method of the Parser class instead of the showAll() method of the CommandWords class directly.

• Run the game and test the new implementation.
