Introduction to Java

Java™ technology consists of both a programming language and a software platform. The core benefit of the Java platform is that it can run on top of several different operating systems, hiding the complexity of the device from the applications and application developers.

Nokia is using Java technology to provide an open application platform for developers, allowing them to create applications for devices that support the technology. A standardized platform gives wide scope for real creativity and frees the developers from dealing with the peculiarities of each different device.

Nokia phones and terminals have extensive Java ME API set. For reference documentation, tutorials and examples see Nokia Java ME Developer's Library .
