Class inheritance Ruby : 

Obviously my parameters for Getemploy.new make no sense, but I jsut did it randomly. That being said. Why is number being returned as an array?
I.e the output is `The employee number is : ["1", "2", "3", "4"] with id : 2 with phone 3 with adress: 4`

    class Employee
      def initialize(n,i,ph,ad)
        @number = n, @id = i , @phone = ph, @adress =ad
      end
      def getInfo
        return @number,@id,@phone,@ad
      end
    end
    class Getemploy < Employee
      def get_data
        return "The employee number is : #{@number} with id : #{@id} with phone #{@phone} with adress: #{@adress}"
      end
    end
    
    employ = Getemploy.new("1","2","3","4")
    puts employ.get_data()
