CLDC

1 The CLDC is combined with one or more profiles to give developers a platform for building applications on embedded devices with very limited resources such as pagers and mobile phones.CLDC Overview http://java.sun.com/javame/technology/cldc/overvi

ew.jsp The CLDC was developed under the Java Community Process as Java Specification Request|

JSR 30JSR 30, CLDC 1.0 http://www.jcp.org/en/jsr/detail?id=30 (CLDC 1.0)

and JSR 139JSR 139, CLDC 1.1 http://www.jcp.org/en/jsr/detail?id=139 (CLDC 1.1).


CLDC - Typical requirements

1 CLDC is designed for devices that have limited processing power,

memory, and graphical capability. Devices typically have the following

features:


CLDC - Typical requirements

1 * At least 160kilobyte|KB Read only memory|ROM allocated for the CLDC libraries and

virtual machine


CLDC - Noteworthy limitations

1 Compared to the Java SE environment, several APIs are absent entirely, and some APIs are altered

such that code requires explicit changes to support CLDC


CLDC - Noteworthy limitations

1 Other examples of limitations depend on the version being used, as some

features were re-introduced with version 1.1 of CLDC.J2ME APIs: Which

APIs come from the J2SE Platform? http://developers.sun.com/mobility/m

CLDC - CLDC 1.0 and 1.1

1 * No finalization. CLDC does not

include the Object.finalize()

method.https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

CLDC - Profiles

1 A profile is a set of APIs that support devices with different capabilities and resources within the CLDC framework to provide a complete Java application environment. There are specific profiles for devices

ranging from vending machines to set-top boxes, with the mobile phone profile MIDP

being the most prevalent.Summary of CLDC-Based Profiles
