Motorola Cdma Mobile Phone V680 Function Of The Java Implementation And Improvement,

Java is a sort of Object Orientation programming language, with such characteristics as strongly network-lined, distributing compute, altitudinal security and haleness. Due to it's span platforms characteristic, programs, developed by Java, can write once, run everywhere. Java technology platform includes J2EE(Java 2 Enterprise Edition) , J2SE(Java 2 Standard Edition) and J2ME(Java 2 Micro Edition) , they are widely used in Enterprise applications , desktop applications and mobile applications.Java can develop applications suit for different Operating Systems .Due to it's open, security, span platform and giant society resource, Java technology becomes the actual standard of aptitude mobile-phone software platform. CLDC (Connected Limited Device Configuration) and MIDP (Mobile Information Device Profile) are used in Java mobile-phone software develop platform, they are parts of J2ME.According to the model of Motorola CDMA(Code Divide Multi Address)V680 and the two masterstrokes including mobile-phone's basic tone operation and wireless increment operations, analyzing it's functions in existence, choosing some modules, develop and debug Java programs by SUN's Java 2 SDK platform and J2ME Wireless toolkit 2.2 in this article.Using class Form and it' s module DateField and Imageltem in J2ME, derived class String/stringltem, Class Label, Array, Thread , Timer in J2SE, and media playing function in MIDP, Realized Mobile-Phone's Boot-Strap Menu which includes displaying Date, time, images and playing music. The function of displaying Date/time was mended and the functions of catching pictures and playing ringswere perfected.Using the MIDP' s main subsystem ,Record Management System(RMS) , and it' s Persistence Storage, Data was saved in mobile information devices. Realized the address book of Motorola CDMA V680 by storing, accessing, sorting the data of the database in the mobile information devices.Defining Canvas class and it' s repaintQ method, Drawing lines, text and shapes, Realized the calendar and notebook.Using Short Message Service protocol and Multimedia Messaging Service afford by MIDP, realized the functions of sending and receiving SMS messages, and added the functions of sending and receiving MMS messages in mobile-phones.Consulting the client/server model of network API, using the Generic Connection Framework (GCF) of J2ME defined for network, communicating by HTTP, realized the HttpConnection () with the static state method openQ returning ConnectionO interface by class Connector, mobile-phone can catch pictures and the content of web by URL from server. Realized the function of accessing the data on internet.Mastering the basic of MIDlet programming, studying the GUI (Graphic User Interface), event handling, Persistence Storage, network communication, which were actually applied in mobile-phone developing software, promote the Java technology were applied and used in the area of mobile-phone.
