Circle和Rectangle是具体桥梁类,它们继承了Bridge,实现了draw方法,将调用转发给实现类的fill方法。 在示例的最后,实例化了RedColor和GreenColor,并分别传递给Circle和Rectangle作为参数。然后调用了draw方法,输出了Circle和Rectangle的颜色填充。 通过桥接模式,将抽象部分和实现部分分离开来,可以使得它们可以独立地变化而互不...
ASCII 艺术画门的多行字符串存储在几个常量变量中,比如ALL_CLOSED、FIRST_GOAT和FIRST_CAR_OTHERS_GOAT。使用这些常量的代码,比如第 125 行的print(FIRST_GOAT),即使我们更新了图形也保持不变。通过将多行字符串一起放在源代码文件的顶部,我们将更容易比较它们,以确保图形是一致的。 """The Monty Hall Problem,...
