Why there is no multiple inheritance in Java, but implementing multiple interfaces is allowed

大家好，我是Java新手，当我尝试在Java中使用多重继承概念时，它显示了编译时错误。为什么Java不支持它。我听说过接口关键字，但是不知道为什么Java直接支持它。请帮我解释一下。

多重继承的主要问题(科林和林提到)是钻石问题。

我引述：

The diamond problem is an ambiguity
that arises when two classes B and C
inherit from A, and class D inherits
from both B and C. If a method in D
calls a method defined in A (and does
not override the method), and B and C
have overridden that method
differently, then from which class
does it inherit: B, or C?

多重继承可能真的很难理解。当您拥有两个类的多重继承，而这两个类有冲突的方法时，您如何处理这个问题？

当然，解决方案存在(例如C++)，但Java的创建者认为这是复杂的，而不是真正的Java哲学(使开发变得更容易)。

来自太阳网：

Multiple inheritance--and all the problems it generates--was discarded from Java. The desirable features of multiple inheritance are provided by interfaces--conceptually similar to Objective C protocols.
An interface is not a definition of a class. Rather, it's a definition of a set of methods that one or more classes will implement. An important issue of interfaces is that they declare only methods and constants. Variables may not be defined in interfaces.

• Java语言环境

因为它很难用。相反，Java有EDCOX1 0，什么是更好的解决方案。
