I can't quite figure out what code should go in this constructor, because it doesn't share the same structure as other constructors in the codebase, likeCanvas, which uses an::Initializefunction instead of a constructor. I'm out of my depth here; though I do need a running copy ofcan...

初始化和清理 对于初始化和清理(cleanup),C++引入了 构造器(constructor)的概念,这是一个在创建对象时被自动调用的特殊方法,Java也采用了构造器,并额外提供了“垃圾回收器”; 1、使用构造器确保初始化 )Java中每个类都会有一个initialize()初始化方法:提醒在使用该类对象前,先调用initialize方法;即构造器方法,Java中...
