Amazon Software Development Engineer interview questions

Which of C++, Java languages supports Multiple Inheritance and which does not ? Follow up: What do you think of Java not supporting Multiple Inheritance? C++ supports multiple inheritance of classes, Java (and C#) supports single inheritence of classes and multiple inheritance of interfaces. When C++ added multiple-class inheritence pure OOP was thought to be "the" solution to everything. In the meantime it was proven that class inheritance is good, but it ends up with tightly coupled systems. The more class inheritance you use, the more likely that one small change will have a huge impact on your entire system. Loosely coupled inheritance - interfaces - are considered a much better option these days.
