| 摘 要： | 文章通过比较Java与 C++在多重继承问题上的异同,分析了Java语言不支持多重继承的原因,并使用三种主要技术:转发、接口和向后引用给出了对多重继承的模拟,从而不但实现了多重继承的功能而且提供了比多重继承更简单、灵活,而且更强劲的功能。

| Abstract: | This paper presents the reasons why Java does not support multiple inheritance of classes by comparing the difference of multiple inheritance between Java and C .It also realizes the simulation of multiple inheritance in Java by joint use of three main methods: forwarding, interfaces and back-references.So the functions of multiple inheritance are not only realized,but also a more simple,more flexible and more strong functions than multiple inheritance which are provided in Java. |

| Keywords: | multiple inheritance single inheritance back-references interface forwarding |
