J2ME platform is especially developed for developing application in mobile device.
Thus,
there
is
one
most
common
constraint,
the
limited
resource.
Therefore
the
Java
Virtual Machine (JVM)
used
in
mobile device
is different than the traditional JVM.
It
is
the cut-down
version
of
JVM.
The
JVM
and
API
are
installed
by
default
by
the
manufacturers.
Thus,
it
is already on
the
mobile device
when
the device
is
come out
to
the market.
