# 定义类
class Box
   # 构造器方法
   def initialize(w,h)

   # 访问器方法
   def getWidth

   # 设置器方法
   def setWidth=(value)
      @width = value
   end

# 创建对象
box = Box.new(10, 20)
 
# 让我们冻结该对象
box.freeze
if( box.frozen? )
   puts "Box object is frozen object"
else
   puts "Box object is normal object"
end
 
# 现在尝试使用设置器方法
box.setWidth = 30
box.setHeight = 50
 
# 使用访问器方法
x = box.getWidth()
y = box.getHeight()
 
puts "Width of the box is : #{x}"
puts "Height of the box is : #{y}"
