Advantages and disadvantages of J2ME technology in the field of mobile phone development

As we all know, in mobile phone development” title=”mobile phone development”>mobile phone development, there are J2ME” title=”J2ME”>J2ME, BREW, Symbian, Windows Mobile and other development methods. Compared with these development methods, J2ME technology is a comparative A common technique, here are some simple comparisons of these techniques.

Advantages of J2ME technology:

1 Strong portability

Programs developed using J2ME technology can run ON mobile phones that cannot be manufactured by manufacturers after simple modifications. This is the biggest advantage of J2ME technology.

2 Development speed is fast

Due to the characteristics of Java” title=”Java”>Java language itself, it is not related to the system, so the development speed is very fast. The development cycle of the program is relatively short.

3 Quick start to technology

Because the JAVA language is quite popular, and for those who have a certain JAVA language foundation, the threshold for learning J2ME technology is very low, so the popularity of J2ME technology is very fast.

Disadvantages of J2ME technology:

1 with limited functionality

In order to realize the portability of J2ME technology, J2ME technology cannot realize the functions of the system, such as reading system contents such as phone book and short message. Unable to develop system software on the phone.

2 is slower

Because J2ME technology runs on the basis of JVM, coupled with the limitation of mobile phone hardware, the running speed is relatively slow, but this speed is still acceptable to users.

3 Program size is limited

On mobile phones, programs developed by J2ME technology are greatly limited in program size. For example, the program size of Nokia S40 series is generally limited to 64KB, which greatly limits the functions of J2ME programs.

If there is any inadequacy, you can actively correct it.
