To prepare code for a cellphone, you would use the same compiler
javac.exe as you use for any other Java work on windows.
You would use a cell phone simulator program to debug your code. This
would be provided by the cell phone maker. It would come with a Java
class library of phone-specific classes. The cell phone maker would
also implement a JVM (but not a Javac or a class library) for his
particular cell phone. Basically he recompiles the C core of the JVM
for his microprocessor and implements some hardware specific native
classes.
Finally, there would be a way to download your program into the phone
for final testing. Advanced phones would have a bluetooth connection
for fast loading rather than sending the program in over the air as if
it were an odd phone conversation, consuming airtime minutes.
To get started on the this exploding area, see

and start chasing links and googling for magic technology words you
find.
Handhelds work much the same way, except you usually have a serial
link of some sort for upload, e.g. USB, infrared, wireless Ethernet...
