SPI(Service Provider Interface): 服务提供接口;也就是服务调用方提供的接口,给服务提供方的;API(Application Program Interface): 应用程序接口;也就是服务提供方暴露提供给服务调用方的;也就是对于由服务调用方暴露需要服务提供方实现的就是SPI(比如java.sql.Driver,spring的Cache模块),对于由服务提供方实现暴露服务...

List ArrayList LinkedList Vector Stack Set HashSet LinkedHashSet TreeSet Map HashMap LinkedHashMap TreeMap ConcurrentHashMap Hashtable 19. Collection 和 Collections 有什么区别? Collection 是一个集合接口,它提供了对集合对象进行基本操作的通用接口方法,所有集合都是它的子类,比如 List、Set 等。

HashSet、LinkedHashSet、TreeSet 都是内部持有一个HashMap、LinkedHashMap、TreeMap实现。其中要注意的是，value不是null，而是一个Object对象。Cloneable接口 实现Cloneable接口，必须实现clone方法。但如果只是简单的调用super.clone()的话，实现的仅仅是浅拷贝，即只会复制引用。若想实现真正的“克隆”，或者说“深...
