Subject: refactor sentencelength solution

Hello,This is my solution to the Sentence length solution on the StartProblemspage of the RubyGarden wiki.
I learned a few things from doing this simple exercise and I wasjust wondering if anyone would be willing to help me refactor thecode as a further learning exercise.
I'm not looking for a new solution, I just want to make this existingsolution better, andimprove the OO of the code.
You can post replys to this email, or you can post replyson my blog, where I also have this posted.Either will be very appreciated!
class Evaluator  def initialize(file)    @reg = []    @char = ""    File.open(file, 'r') do |f|      f.each do |line|        @char << line      end    end    split_and_strip(@char)  end
  #split every sentence, then strip the newline characters.  def split_and_strip(str)    str.split(/[.?!]\s*/).each do |x|      @reg << x.gsub("\n", " ")    end  end
  def average?    @char = @reg.inject(0) do |m,o|      m + o.length    end    print "\nThe average sentence is ", (@char / @reg.length), "characters long."  end
  def biggest?    @char = @reg.inject(@reg[0].length) do |m,o|      if m >= o.length        m      else        o.length      end    end    print "\nThe biggest sentence is ", (@char), " characters long."  end
  def smallest?    @char = @reg.inject(@reg[0].length) do |m,o|      if m <= o.length        m      else        o.length      end    end    print "\nThe smallest sentence is ", (@char), " characters long."  endend
e = Evaluator.new("words.txt")e.smallest?e.average?e.biggest?
