and first-class member in Java; Program to interface not to class; Prefer
interface inheritance to implementation inheritance. In short, interface is
a much better solution than multiple inheritance, Java learned the lesson.

发帖数: 3271 | 10 问得莫名其妙，“用”INTERFACE”和多继承一定矛盾吗，C++难道不用接口？

发帖数: 34805 | 11 C++是没有接口这个概念，虽然你可以定义一个只有虚函数的母类。
另外很重要的是C++不是同根继承(所有java类继承Object类)，
这也使得实现上产生困难。
