public static Singleton getInstance() { if(instance==null) { instance = new Singleton(); } return instance; } } 名词解释: 1. 泛型相关知识点: 试题来源: 解析 答:即参数化类型,允许程序创建集合时指定集合元素的类型。在定义方法、类、接口时使用类型形参,类型形参将在声明变量、调用方法、创建对象时动...
The dependencies declaration order in a service's constructor causes the service to receive a private instance of a depended service instead of the singleton service exported in the corresponding module. It also alters the instantiation order, causing the dependant service to be instantiated before the...
