在C++中,使用virtual关键字声明虚函数。 在Java中,每个公共、非静态和非最终方法都是虚函数。 Python方法始终是虚拟的。 Example: C++ class base { virtual void print() { cout << "This is a virtual function"; } } Java class base { void func() { System.out.printIn("This is a virtual func...

In the past decade Java has emerged in wide use partially because of its similarity to C++, but perhaps more importantly because of its implementation using a virtual machine that is intended to run code unchanged on many different platforms. This last feature has made it very attractive to lar...
