What's Java Mobile Application?

A mobile device (also known as convergence, portable device, handheld,(PDA) or simply pocket) is a handheld computing device, usually comprising a small video screen to the user exit and miniature keyboard or a touch screen for user input. In the case of personal digital assistant (PDA), the input and output are combined into a touch screen interface. Smartphones and PDA are popular with those who need help and comfort of a conventional computer, in environments where carrying one would not be practical.

Mobile Java application is simply a collection of components that are compatible with a Java Micro Edition (JME), a platform designed to run on a specific need for a particular device. There are many applications that are compatible with JME, many of them are games (the most popular Java mobile applications). Almost every game we play in our mobile devices are created with JME technology. A developer needs some tools to create a new mobile application and the most important of these is JME, also a mobile device emulator. A mobile device emulator is a program that simulates all the basic operations such as entry and exit of a cell phone or PDA. Let's look at development tools that Nokia offers mobile java developers.
Nokia offers a wide range of tools designed to help developers to efficiently create high-quality Java applications. The developers started with the Eclipse IDE used in conjunction with NetBeans IDE EclipseME or used in conjunction with NetBeans Mobility Pack. These tools provide functionality for the creation and manipulation of information, mobile device profile (MIDP) applications. Nokia SDK can be integrated into these tools. The SDK to facilitate application testing on a PC without the need for a device emulator for the Series 40 platform, the S60 and Series 80 platform and the Nokia prototype SDK for Java ME ™ emulator. The SDK also provides complete API documentation and sample applications that can work with Java technology for Nokia devices as simple as possible.
Key Benefits:

* SDK support for the Eclipse and NetBeans IDEs.
* Development of MIDP and Personal Profile (PP) applications.
* Additional MIDP development tools.
* Comprehensive support for PC-based testing of connected applications.

The Toolbox:

* The Eclipse IDE with EclipseME or the NetBeans IDE with Mobility Pack.
* Series 40 Platform 2.0 SDKs.
* S60 Platform SDKs for Symbian OS, for Java.
* Series 80 Platform SDKs for Symbian OS, for Java.

Developers just need a collection of libraries, and an emulator. Moreover, as NetBeans or Eclipse IDE is very useful. The end product of a user need is a jar file. JAR file or a file is a collection of Java classes and metadata that is compressed into a file. JAR files are very useful in the distribution of Java applications. You can find plenty of mobile Java applications on the network, someone just download, connect your phone to your PC and download the file. JAR on your mobile. And much appreciated!. You can also download your favorite Java applications from the network directly on your mobile.
