Join Kevin Skoglund for an in-depth discussion in this video Reader/writer methods, part of Ruby Essential Training.
At the end of the last movie, we saw how we could access our instance…variables using methods.…I want to explore that idea a little further in this movie by looking at…reader and writer methods.…Now this is a very common feature of object-oriented programming languages,…sometimes in other languages, they're called getter and setter methods.…Either one is fine.…You can use either name, typically in Ruby, we're going to call them reader…and writer methods.…So, here is the code where we left off inside classes.rb, what we're looking…for is a pairing of something that will set a value for us and something that…will get a value for us, and that's exactly what we already have with our two methods.…
The first one is a setter method or a writer method.…So we're setting the value of noise equal to a value, and this is the classic…format for what a setter method would look like, set_noise equal to a value. It sets it for us.…Then we have make_noise.…Typically, we would call this get_noise.…It's a getter method.…
