According to Suns definition: J2ME is a highly-optimized Java operating environment targeted at consumer electronic devices such as cell phones and video phones, digital set-top boxes, car navigation systems, and more. J2ME technology was officially launched at the JavaOne Developer Conference in 1999, porting the platform-independent features of the Java language to small electronic devices, allowing applications to be shared between mobile wireless devices. When designing its specifications, J2ME follows the basic principle of creating a single development system for various devices. So J2ME first divided all embedded devices into two types: one is an embedded device with limited computing power and limited power supply (such as PDA and cell phone); the other is relatively better computing power. And please use embedded devices (such as air conditioners, refrigerators, set-top boxes) that are relatively adequate in power supply. Because of these two types of embedded devices, Java introduced a concept called Configuration, and then defined the Connected Limited Device Configuration (CLDC) specification for the above-mentioned embedded devices with limited computing power and limited power; Devices are regulated as Connected Device Configuration (CDC) specifications. In other words, J2ME first divides all embedded device configuration concepts into two abstract patterns. In fact, here we can regard Configuration as the specification of J2ME for two types of embedded devices, and these specifications define the specifications of these devices, such as computing power, power supply capacity, memory size, etc., as well as specifications.
