Differences Between Core Java and Java for J2ME
Major Differences are :
Floating-point math is missing in J2ME. MIDlet cannot use any
floating-point data types or calculations.
Absence of finalize() method
in J2ME.
Reduced number of error-handling
exceptions in J2ME.
JVM for small computing devices requires
a custom class loader that
is supplied by the device manufacturer and cannot be replaced or modified.
We cannot
group threads. All threads are handled at the object level.
The class
file verification is
replaced with two processes called Preverificaton and Validation.
Preverification occurs prior to loading the MIDLet’s and Validation occurs
after loading the MIDLet.
