    Different Mobile phone vendor companies use different platforms
    for developing applications for their own platform.
    We’ll discuss about a open “Legacy” platform as an example which
    is J2ME
    Java Platform, Micro Edition, or Java ME:
    It is a Java platform designed for embedded systems (mobile
    Devices are one kind of such systems) .
    Target devices range from industrial controls to mobile phones 
    with Java (KVM support).
    Formerly known as Java 2 Platform, Micro Edition (J2ME).
    For details:
    http://en.wikipedia.org/wiki/Java_Platform,_Micro_Edition
    Nokia, Samsung, Sony Ericsson and many other vendors supports J2ME for
    applications and games development
