Answer 1

Do all jar files run on mobiles???

No

is there a certain way of programmings am supposed to use ??

Yes , you need to use j2me for specific MIDP CLDC platrofm . have a look here

are there specific classes am supposed to use???

You can use the classes available over the platform , alternatively you can also add the external library

Answer 2

Some OS's like Symbian Can run java package file ie .jar files.

And Android lacks that capability.

Phones with MDIP runs .jad files that is a Java app made using the J2ME API.

Android generate Dalvik Bytecode and run .apk packages on the phone.

Answer 3

Easy, seems like your about to have a stroke. Start reading some articles about getting started on J2ME, try these ones out:

You have to know, that depends on the your orientation of you application, not all applications runs in all cell phones, is like in computers, a Windows application won't work on Linux, unles you use a Virtualizer. My point is, start reading all the documentation you you cant, and take it slow.
