构建此处理代码的更好方法是什么？

Question

我有这个处理代码可以正常工作，但是对象实例化和case语句有很多重复的代码......在速度/编写代码紧凑性方面有没有更经济的方法呢？

使用Inheritance和Polymorphism。这两个面向对象的编程概念应该可以帮助您删除大量的代码大小（因为您将使用方法/函数而不是代码重复）。一旦你使用了这些，你也可以使用Solid的数组（如果我们要调用那些实体的父类），并进一步简化你的很多代码。使用数组存储text()调用的参数，您甚至不需要切换案例语句。

以上所有内容只会提高您的代码可理解性和可管理性。它不会影响性能（好的，函数调用的开销很小，但在这种情况下，它没有实际意义）。
