Well, anywhere before you actually use the new method.

If you would move the class String...end block to the end of the code,
the following would not work:

class String
  def capitalize_each
    self.split(" ").each{|word| word.capitalize!}.join(" ")
  end
  def capitalize_each!
    replace capitalize_each
  end
end

print "Type some words here: "
str = gets
print "This is the capitalize method: "
puts str.capitalize
print "and this is the custom made capitalize_each method: "
puts str.capitalize_each
print "The original string: "
puts str
str.capitalize_each!
print "Now it's changed: "
puts str
puts "(any key to exit)"
a = gets
