通过应用面向对象的设计方法来管理单个的 J2EE 组件实现类及接口如何变化，可以更好地对此进行处理。
This can be better handled by applying techniques of object-oriented design to manage how individual J2EE component implementation classes and interfaces evolve.
我们已经了解到，要对软件进行恰当设计，以将流程序列逻辑、策略、基本计算、人机接口和数据管理分离开来。
We've learned to design software to separate process sequencing logic, policy, basic computation, human interface, and data management.
尽管内存管理看起来可能无足轻重，但是恰当设计的接口能够产生高效、简单和可移植的代码 —— 这其中每个特性都需要进行内存管理才能实现。
Although memory management may appear trivial, a properly designed interface can produce code efficiency, simplicity, and portability -- none of which may be achievable otherwise.
