If you understand how multiple inheritance is implemented, you will be able anticipate these consequences and deal with them in your code.
Perl supports single or multiple inheritance hierarchies, encapsulation, and polymorphism, but only through external modules or programmer agreement.
Other languages have addressed this with traits or full-blown multiple inheritance, but we did not want to fundamentally change the Java object model.
For example, all classes inherit from object, so any case of multiple inheritance provides more than one path to reach object.
C++ supports multiple inheritance, and Java allows a class to implement multiple interfaces.
Item 24: Understand the costs of virtual functions, multiple inheritance, virtual base classes, and RTTI?
To reduce the complexity and simplify the language, multiple inheritance is not supported in java.
Experienced programmers know to avoid this evil because they know that deep inside the dark forest of inheritance is the evil queen, multiple inheritance.
But all new style classes inherit from object, therefore diamonds are unavoidable and inconsistencies shows up in every multiple inheritance graph.
C++: I have already mentioned multiple inheritance, virtual base classes, and templates.
Interfaces are also considered to be the way Java gains some of the benefits of multiple inheritance without the drawbacks.
Most of the uses of inheritance can be simplified or replaced with composition, and multiple inheritance should be avoided at all costs.
An extended class is always dependent on a single base class, that is, multiple inheritance is not supported.
Instead I will focus on the common base class, access to the base class, multiple inheritance, interfaces, late binding, and other related topics.
It does so by implementing its own__getattribute__ method for searching classes in a predictable order that supports cooperative multiple inheritance.
Although it was not their primary intent, default methods also allow multiple inheritance of behavior(but not state).
One thing that really surprised me about Go- a supposedly simple language- is that you can even do multiple inheritance.
Item 24: Understand the costs of virtual functions, multiple inheritance, virtual base classes, and RTTI.
Features are already being lined up for C 7.2 and 8.0 including nullable reference types and limited multiple inheritance.
This will allow a tag have more than one parents, something like multiple inheritance in some OOP languages.
