Success! Thanks to self and the dot operator, it’s now clear to Ruby (and everyone else) that we’re making calls to the attribute writer methods, not assigning to variables.

And since we’re going through the accessor methods, that means the validation works, without any duplicated code!

When “self” is optional

Right now, our print_pay_stub method accesses the @name and @salary instance variables directly:

class Employee

def print_pay_stub

puts "Name: #{@name}"

pay_for_period = (@salary / 365.0) * 14

formatted_pay = format("$%.2f", pay_for_period)

puts "Pay This Period: #{formatted_pay}"

end
