Introduction to J2ME
21 May 2007J2ME (Java 2 Micro Edition) is the environment of development for mobile or portable devices, as cell phones and palmtops. As Java language is very popular, the adaptation to J2ME is not complicated. So, many kinds of applications have been created for those devices, as games and schedules. Companies have won with that because, since their devices have a JVM (Java Virtual Machine), it’s possible to implement applications in every device, being hardware capacity the only limit.
J2ME platform contains configurations and libraries made especially to work in portable devices. Thus, developer has a better facility to handle with the limitations of processing and memory, for example. An example of this is the configuration called CLDC (Connected Limited Device Configuration), destined to devices with very limited hardware resources, as 16 bits processors and 512 KB memories. This configuration contains a JVM and a basic set of libraries that allows Java application to work in devices with those characteristics.
