下列选项中,用于实现接口的关键字是 ( ) A. interface B. implements C. abstract D. class 相关知识点: 试题来源: 解析 B 正确答案:B解析:interface是定义接口时用的关键字;abstract是用来声明抽象类或方法的;class是声明一个类的关键字;implements是用来实现接口的关键字。所以选项B是正确的。
interface class B; ... endclass //普通类定义 class C; ... endclass //接口类的多继承 class D extends B implements A,B; ... enclass 从上面可以看到,class D除了继承于B以外,还可以实现接口类A和B,class D内包含了class A、B、C所有的属性和方法,因此实现多继承的效果。
