Know the J2ME Technology as the Application of GPS Support

J2ME is a combination that exists between a set of Java interfaces that are often referred to as the Java API (Application Programming Interface) with JVM (Java Virtual Machine) designed specifically for the instrument, namely the JVM with limited space. The combination is then used to perform manufacturing applications that run on mobile devices.
J2ME itself basically consists of 3 parts, namely the configuration, profiles, and packages are optional packages. Here's an explanation of the three parts of J2ME :


Configuration is the part that contains the JVM and some other class library. There are 2 pieces of configuration that is provided by SUN Microsystems, the CLDC (Connected Limited Device Configuration) and CDC (Connected Device Configuration). The target device from the CLDC configuration is the small tools, such as cellular phones, PDAs, and pagers. While the CDC is a superset of CLDC, so all the classes are defined in CLDC will exist also in the CDC. Configuration has been provided by the company's tools and placed in the relevant instrument that is ready for use.


Profile is part of the configuration expansion. That is, besides a set of classes contained in the configuration, there are also specific classes are defined again in the profile. The profile is very popular is its use of artificial profiles Sun Microsystems, namely MIDP (Mobile Information Device Profile). Profiles are provided by the company's tools and placed in the relevant instrument that is ready for use.

Optional packages are additional packages required by the application so that when the deployment process for those packages need to be distributed also some part of the application concerned. In contrast to the configuration and profile, if the optional packages are not provided by the companies concerned.
