J2ME - a colorful technology in a colorful field
Tomorrow's calculations will enter the popularization of the time. Various consumer electronics, including smartphones, PDAs, Web-TV, future information appliances, etc. will achieve calculations anytime, anywhere. This is an exceptionally broad and colorful area, and its equipment is extremely diversified and will be in the network, Java technology's cross-platform and network functions are widely used here. This is J2ME, this colorful technology in this colorful field. However, the diversity of this field and the complexity of J2ME standards are easy to make the initial contact. If he tries to write a program that can run on its own PDA, it is very likely to encounter a lot of difficulties, because the existing old technologies are likely to be abandoned, and the standard for PDA has not been completed, a variety of diverse Standards and technology itself is also rapidly evolving. To this end, the focus of this paper is not in the specific coding details, but is more accurately expressed as the architecture of J2ME, helping the reader to understand and grasp these complex criteria. And from the macro-described development, the status quo and prospects of developing J2ME applications on mobile information devices are analyzed, try to make readers to grasp complex situations in the whole game, and prepare for future development.
