add junior method and roll_call print method

[noahpatterson]

I want to be able to do the commented version above the uncommented 'roll_call' method, but I am not sure how. That 'include?' bit may be wrong as well. Thanks!

If you want to do this, you could convert the string "senior" to a method senior? and reduce the line count.

def roll_call(students, grade)
  puts "#{grade.capitalize}:"
  students.select { |student| student.send("#{grade}?".to_sym}.each do |stu|
    puts "* #{stu}"
  end
end

I think you were SO CLOSE on the commented method. Let me know if it makes any sense.

I created an example fiddle for you: http://rubyfiddle.com/riddles/09598/2

class SaysHello
  def speak
    "Hello!"
  end
end

speaker = SaysHello.new
puts speaker.speak
puts speaker.send(:speak)
puts speaker.send("speak".to_sym)

Fixed, love the send and to_sym! Thanks
