# 1. Implement encapsulation to achieve the following
# You want to post on facebook to say:
# "hello world" visible to everyone
# "hello friends" visible only to your friends
# "hello new people" visible only to friends of friends
# create class FbPost and User
# FbPost should include methods to print posts like "hello world" etc

class FbPost
  def user_msg_everyone
    puts "hello world"
  end
  private
  def msg_to_friends(message)
    puts message
  end
  protected
  def msg_friends_of_friends(message)
    puts message
  end
end
class User < FbPost
  def access_msg
    msg_to_friends("hello friends")
    FbPost.new.msg_friends_of_friends("hello new friends")
  end
end
# user = FbPost.new
# user.user_msg_everyone
users = User.new
users.user_msg_everyone
users.access_msg
