language is a general-purpose, concurrent, class-based, object-oriented programming
language. It is designed to be simple enough that many programmers can achieve fluency in the
language. Java is related to C and C++ but is organized rather differently, with a number of
language. Java is related to C and C++ but is organized rather differently, with a number of
aspects of C and C++ omitted and a few ideas from other languages included.
The PersonalJava
TM
Application Environment (PJAE) is a Java application environment that
executes software written in the Java programming language. The PJAE addresses the software
needs of networked applications running on personal consumer devices such as set-top boxes
and smart phones rather than desktop computers.

JAVA IMPLEMENTATION ON THE NOKIA 9210 COMMUNICATOR
The Nokia 9210 Communicator is the first Java-capable Nokia phone. At a general level, the
objectives of using Java in the Nokia 9210 Communicator are:
•
To start fulfilling the promises of Java language: ease of programming, portability and
safety. A simpler and safer language means easier programming, less errors, less testing
and less debugging.
