本文介绍了在基于Java 2 Micro Edition(J2ME)规范上开发一个手机的模拟系统。该系统充分体现了J2ME的体系架构和各模块的特点,设计采用了面向对象的方法,基本模拟实现了手机的部分功能,并着重讨论设计开发过程中的问题。-In this paper based on Java 2 Micro Edition (J2ME) specification developed an analog phone system. The system fully reflects the J2ME architecture and the characteristics of each module, designed using object-oriented approach, the basic simulation to achieve some of the functions of the phone, and focus on the design and development process issues.
