**Java 泛型（Generics）** 是 JDK 5 中引入的一个新特性。使用泛型参数，可以增强代码的可读性以及稳定性。

编译器可以对泛型参数进行检测，并且通过泛型参数可以指定传入的对象类型。比如 `ArrayList<Persion> persons = new ArrayList<Persion>()` 这行代码就指明了该 `ArrayList` 对象只能传入 `Persion` 对象，如果传入其他类型的对象就会报错。

一般模块之间都是通过通过接口进行通讯，那我们在服务调用方和服务实现方（也称服务提供者）之间引入一个“接口”。
一般模块之间都是通过接口进行通讯，那我们在服务调用方和服务实现方（也称服务提供者）之间引入一个“接口”。

当实现方提供了接口和实现，我们可以通过调用实现方的接口从而拥有实现方给我们提供的能力，这就是 API ，这种接口和实现都是放在实现方的。
