The configuration defines the basic run-time environment as a set of core classes and a specific JVM that run on specific types of devices. Currently, two configurations exist for J2ME, though others may be defined in the future:
- Connected Limited Device Configuration (CLDC) is used specifically with the KVMfor 16-bit or 32-bit devices with limited amounts of memory. This is the configuration(and the virtual machine) used for developing small J2ME applications. Its sizelimitations make CLDC more interesting and challenging (from a development point ofview) than CDC. CLDC is also the configuration that we will use for developing ourdrawing tool application. An example of a small wireless device running smallapplications is a Palm hand-held computer.
- Connected Device Configuration (CDC) is used with the C virtual machine (CVM) and is used for 32-bit architectures requiring more than 2 MB of memory. An example of such a device is a Net TV box.
