As we all know, in mobile phone development, there are J2ME, BREW, Symbian, Windows Mobile and other development methods, and these development methods, J2ME technology is using a more common technology, the following is a few simple comparisons of these technologies. Advantages of J2ME Technology: L Transplant Strong use of J2ME technology development of the program, can be modified after a simple, not the manufacturer's mobile phone, this is the J2ME technology the biggest advantage. L Rapid development because of the characteristics of the Java language itself, and the system is not related to a small, so the development of fast. The development cycle of the program is relatively short. L Technology Getting started fast because of the popularity of the Java language, and for people with a certain Java language Foundation, the threshold of learning J2ME technology is very low, so J2ME technology popularization speed quickly. Disadvantages of J2ME technology: l function Limited in order to realize the portability of J2ME technology, J2ME technology can not realize the functions of the system, such as reading phone book, short message and other system contents. Unable to develop the system software on the phone. L slower speed because the J2ME technology runs on the JVM, plus the limitations of the phone's hardware, the speed is relatively slow, but the user can still accept it. L Program Size Limited to the mobile phone, J2ME technology Development Program in the program size is greatly limited, such as the Nokia S40 series of program size generally limited to 64KB, this greatly limits the function of the J2ME program.
There is no shortage of places, we can actively correct.
