我在编写有关机场服务的代码时遇到问题，其中包含两个类、构造函数、运算符等。我不允许更改主要功能，那是我被分配要做的事情。 我被“没有匹配的‘AirportService’初始化构造函数”问题难住了，除非我更改主要功能，否则我似乎无法解决这个问题。我能对如何解决这个问题有任何见解吗？ 这是我正在使用的代码

我试图修复复制构造函数但无济于事，也许我只是做错了。就我而言，唯一不允许的修复方法是将“as”值分配给 AirportService s2。 在不更改主要功能代码的情况下，是否可以解决此问题？
类
AirportServiceAirportService s2;
要么声明构造函数，要么使用类的现有构造函数的参数重写声明。
