代码说明:

创建类的实例的最常见的方式是用new语句调用类的构造方法。在这种情况下,程序可以创建类的任意多个实例,每执行一条new语句,都会导致Java虚拟机的堆区中产生一个新的对象。假如类需要进一步封装创建自身实例的细节,并且控制自身实例的数目,那么可以提供静态工厂方法。

  • 这本是为你
    This book is for you if You re no "dummy," and you need to get quickly up to speed in intermediate to advanced C++ You ve had some experience in C++ programming, but reading intermediate and advanced C++ books is slow-going You ve had an introductory C++ course, but you ve found that you still can t follow your colleagues when they re describing their C++ designs and code You re an experienced C or Java programmer, but you don t yet have the experience to develop nuanced C++ code and designs You re a C++ expert, and you re looking for an alternative to answering the same questions from your less-experienced colleagues over and over again C++ Common Knowledge covers essential but commonly misunderstood topics in C++ programming and design while filtering out needless complexity in the discussion of each topic. What remains is a clear distillation of the essentials required for production C++ programming, presented in the author s trademark incisive, engaging style.
