Comprehension Questions

Question	Answer
When does the initialize method run? What does it do?	The initialize method runs when that class is instantiated, like Class.new. The method defines the parameters the program accepts and stores in each instance of the class.
Why do you imagine we made our instance variables readable but not writable?	They were only made readable so we could not overwrite the data stored in the instance variables.
How would your program be different if each planet was stored as a Hash instead of an instance of a class?	Overall, I would say I would have less control over my program if each planet were stored in a hash instead of an instance of a class. The program would also be much less clear and easy to read/understand, especially if someone else besides me were to read it.
How would your program be different if your SolarSystem class used a Hash instead of an Array to store the list of planets?	I would have to access the list of planets differently in each method where I currently use the array.
There is a software design principle called the SRP. The Single Responsibility Principle (SRP) says that each class should be responsible for exactly one thing. Do your classes follow SRP? What responsibilities do they have?	Yes, each class stores information about a specific thing. The Planet class stores information specific to each planet, and the SolarSystem class contains a collection of planets - it stores information and performs operations related to planets within the solar system, such as listing all of the planet names.
How did you organize your require statements? Which files needed requires, and which did not? What is the pattern?	I only put my require_relative statements in the driver code (main.rb) and included the statement for each class I was using for the program. The driver code needs the requires statements because that is where the classes 'interact' with the program and each other.

[jmaddox19]

Very cool to decide to put the checking into separate methods!

[jmaddox19]

Makes it so much easier to read!

[jmaddox19]

Is there a reason why you aren't calling this one in the constructor like you call massChecker?

[jmaddox19]

To clarify, a negative distance can be entered because this isn't called.
