The Connected Limited Device Configuration (CLDC) is a specification of a framework for Java ME applications targeted at devices with very limited resources such as pagers and mobile phones. The CLDC was developed under the Java Community Process as JSR 30 (CLDC 1.0) and JSR 139 (CLDC 1.1). Image File history File links This is a lossless scalable vector image. ...

Noteworthy limitations

• Some interesting additions to CLDC 1.1 is the support for floating points and weak references. Also, the amount of minimum memory needed was raised from 160 KiB to 192 KiB.

A floating-point number is a digital representation for a number in a certain subset of the rational numbers, and is often used to approximate an arbitrary real number on a computer. ... In computer programming, a weak reference is a reference that does not protect the referent object from collection by a garbage collector. ...

Profiles

Mobile Information Device Profile

Designed for cell phones, it supports an LCD orientated GUI API, with MIDP 2.0 including a basic 2D gaming API. Applications written to use this profile are called MIDlets. Almost all new cell phones come with a MIDP implementation, and it is now the de facto standard for downloadable cell phone games.

Information Module Profile

The Information Module Profile (JSR 195) is designed for vending machines, network cards, routers, telephone boxes and other systems with either simple or no display and some form of limited two way network access. Only APIs for application creation, storage, and network access are defined. These are a subset of the javax.microedition.io, rms and midlet packages in MIDP. Siemens Mobile and Nokia put forward this specification to the JCP. IMP stands for the Information Module Profile. ...

General APIs

java.io

A streamlined version of the java.io package found in the standard edition for doing Input/Output operations.

java.lang

Contains classes thought applicable to most java programs. This package contains standard java types like Integers and Strings as well as basic exceptions, math functions, system functions, threading and security functions.

java.util

A streamlined version of the java.util collection library. This package contains the collection classes like Vector and Hashtable. It also contains calendar and date classes.
