修饰符用于表示所修饰的类是不完整的，并且它只能用作基类。抽象类与非抽象类在以下方面是不同的：抽象类不能直接实例化，并且对抽象类使用 new运算符是编译时错误。虽然一些变量和值在编译时的类型可以是抽象的，但是这样的变量和值必须或者为null，或者含有对非抽象类的实例的引用（此非抽象类是从抽象类派生的）。允许（但不要求）抽象类包含抽象成员。抽象类不能被密封。当从抽象类派生非抽象类时，这些非抽象类必须具体实现所继承的所有抽象成员，从而重写那些抽象成员。在下面的示例中abstract class A{public abstractvoid F();}abstract class B:A{public void G() {}}class C: B{public overridevoid F() {// actualimplementation of F}}抽象类 A 引入抽象方法 F。类 B 引入另一个方法 G，但由于它不提供 F 的实现，B 也必须声明为抽象类。类C 重写F，并提供一个具体实现。由于 C 中没有了抽象成员，因此可以（但并非必须）将 C 声明为非抽象类。接口(i<img src ="http://blog.csdn.net/shenhaha001/aggbug/2393133.aspx" width = "1" height = "1" />Mon, 05 May 2008 21:56:00
