What is a Java Mobile Application

A mobile device (also known as converged device, handheld device, handheld computer, "Palmtop" or simply handheld) is a pocket-sized computing device, typically comprising a small visual display screen for user output and a miniature keyboard or touch screen for user input. In the case of the personal digital assistant (PDA) the input and output are combined into a touch-screen interface. Smartphones and PDAs are popular amongst those who require the assistance and convenience of a conventional computer, in environments where carrying one would not be practical.Java mobile application is nothing but a collection of components supported by a Java Micro Edition (JME) platform created to run in a specific requirement for a particular device.

There are many application which are supported by JME, many of them are games (the most famous java mobile applications). Almost all of the games that we play in our mobile devices are created with JME technology. A developer need some tools to create a new mobile application and the most important of them is JME, also a Mobile device emulator. A Mobile device emulator is an application that simulates all the basic operations like input and output of a cell phone or PDA. Lets see the developers tools that nokia offers to the java mobile developers.
Nokia has a range of tools designed to make it easy for developers to efficiently create high-quality Java applications.
Developers start with either the Eclipse IDE used in conjunction with EclipseME, or the NetBeans IDE used in conjunction with NetBeans Mobility Pack. These tools provide features for creating and packaging mobile information device profile (MIDP) applications. Nokia SDKs can then be integrated with these tools. The SDKs facilitate application testing on a PC, without the need for a device, with emulators for the Series 40 platform, the S60 platform, and the Series 80 platform, as well as the Nokia Prototype SDK for Java™ ME emulator. The SDKs also provide full APIs, documentation, and example applications to make working with Java technology for Nokia devices as straightforward as possible.
