Question

Is it good in practice to create two different classes in one ruby script file like this?

Ruby file name – XYZ.rb

class Car
  .........
  .........
end

class Bike
  .........
  .........
end

What will be the advantage or disadvantage of this?

Answer 1

The main advantage of multiple classes in one file is that you can quickly try something and hack stuff together. I’d suggest not doing so when coding on a more serious project or work, because as Sergio Tulentsev stated, you can get problems in environments with autoloading. Another disadvantage is that you lose track of what classes are located in what file.
