multiple-inheritance

问题 If I have two interfaces , both quite different in their purposes , but with same method signature , how do I make a class implement both without being forced to write a single method that serves for the both the interfaces and writing some convoluted logic in the method implementation that checks for which type of object the call is being made and invoke proper code ? In C# , this is overcome by what is called as explicit interface implementation. Is there any equivalent way in Java ? 回答1:

问题 In an attempt to fully understand how to solve Java\'s multiple inheritance problems I have a classic question that I need clarified. Lets say I have class Animal this has sub classes Bird and Horse and I need to make a class Pegasus that extends from Bird and Horse since Pegasus is both a bird and a horse. I think this is the classic diamond problem. From what I can understand the classic way to solve this is to make the Animal , Bird and Horse classes interfaces and implement Pegasus from

问题 I know that multiple inheritance is not allowed in Java and C#. Many books just say, multiple inheritance is not allowed. But it can be implemented by using interfaces. Nothing is discussed about why it is not allowed. Can anybody tell me precisely why it is not allowed? 回答1: The short answer is: because the language designers decided not to. Basically, it seemed that both the .NET and Java designers did not allow multiple inheritance because they reasoned that adding MI added too much

问题 Since multiple inheritance is bad (it makes the source more complicated) C# does not provide such a pattern directly. But sometimes it would be helpful to have this ability. For instance I\'m able to implement the missing multiple inheritance pattern using interfaces and three classes like that: public interface IFirst { void FirstMethod(); } public interface ISecond { void SecondMethod(); } public class First:IFirst { public void FirstMethod() { Console.WriteLine(\"First\"); } } public class

问题 I\'m pretty much new in Python object oriented programming and I have trouble understanding the super() function (new style classes) especially when it comes to multiple inheritance. For example if you have something like: class First(object): def __init__(self): print \"first\" class Second(object): def __init__(self): print \"second\" class Third(First, Second): def __init__(self): super(Third, self).__init__() print \"that\'s it\" What I don\'t get is: will the Third() class inherit both
