This feature enables an interface to define static members. This enables interfaces to define operators that must be provided by implementing types.
先说说interface和abstract method语法中需要注意的地方。 Interface: 1. An interface can contain fields, but these are implicitly static and final. 2. You can choose to explicitly declare the methods in an interface as public, but they are public even if you don’t say it. 3. Interface cannot...

接口用关键字 interface 来声明。 2 . interface 是完全抽象的,只能声明方法,而且只能声明 public 的方法,不能声明 private 及 protected 的方法,不能定义方法体,也不能声明实例变量 。然而, interface 却可以声明常量变量 。但将常量变量放在 interface 中违背了其作为接口的作用而存在的宗旨,也混淆了 interface 与...

abstract class X implements Y { // implements all but one method of Y } class XX extends X { // implements the remaining method in Y } In this case, class X must be abstract because it does not fully implement Y, but class XX does, in fact, implement Y. Class Members An abstrac...
