J2ME


Java Platform, Micro Edition (Java ME) provides a robust, flexible environment for applications running on mobile and embedded devices: mobile phones, set-top boxes, Blu-ray Disc players, digital media devices, M2M modules, printers and more.

Java ME technology was originally created in order to deal with the constraints associated with building applications for small devices. For this purpose Oracle defined the basics for Java ME technology to fit such a limited environment and make it possible to create Java applications running on small devices with limited memory, display and power capacity.

J2ME Connected, Limited Device Configuration (CLDC)
• specifies the Java environment for mobile phone, pager and wireless devices
• CLDC devices are usually wireless
• 160 - 512k of memory available for Java
• typically has limited power or battery operated
• network connectivity, often wireless, intermittent, low-bandwidth (9600bps or less)

J2ME Connected Device Configuration (CDC),
• describes the Java environment for digital television set-top boxes, high end wireless devices and • automotive telematics systems.
• device is powered by a 32-bit processor
• 2MB or more of total memory available for Java
• network connectivity, often wireless, intermittent, low-bandwidth (9600bps or less)
