Ruby Naming Convention > Method Naming

snake_case

• Should be all in lowercase
• Preferably a verb e.g. get_car(), purchase(), book()
• If the name contains multiple words, it should be separated by underscores (_) e.g. get_json()
• Clear and descriptive method names without abbreviations are preferred.

class Person
    def get_height(self)
        return self.height
    end
end

Private methods

To make a method private, use the keyword private above it anywhere in the class.

class Person

    def get_height(self)
        return self.height
    end

    private

    def get_weight(self)
        return self.height
    end

end

Above, get_height() is public, get_weight() is private. You may use the public key word below private, but generally this is not done.
