“Java

Micro
Edition
(J2ME) combines
a
resource-constrained
JVM
and
a
set
of
Java APIs for developing applications for mobile devices.” [17]
J2ME
is
one
of
programming
language
platform
developed
by
Sun
Microsystems
along
with
another
Java

platform.
There
are
three
editions
of
Java
2
Platform,
Java
2
Enterprise Edition (J2EE), Java 2 Enterprise Edition (J2SE), and Java 2 Micro Edition
(J2ME). J2EE
has the
most comp lete Java API.
It
is
usually
used
in servers. J2SE API
is
a
subset of J2EE API. J2SE
is the Java platform that
is
most commonly
used. J2ME, on
the other hands, has smaller subset of Java API but it also has another set of Java API that
is not provided in other Java platform. API is also known as library.
