1. Can I create application to save something to the cell/device and read it later on ?
2. Do we have to care about the type of device ? like the resolution and etc. Since Java should be write once run anywhere.

Any of you have recommendation which device is the best to program J2ME ?
(I mean by using this device then worries about things like memory,CPU power, resolution, etc can be reduced)

It makes more sense to allow the user to have that control rather than the developer.

The developer has the choice in the openRecordStore method call. The authmode parameter can be AUTHMODE_PRIVATE (which mimics the MIDP 1.0 behaviour) or AUTHMODE_ANY (where any MIDlet on the device can access the database).

is J2ME easier to learn and apply or harder if one has good and strong foundation at J2SE?

So if the developer uses the AUTHMOD_ANY constant, does that mean that his/her MIDlet can access any database on the device, or does it give permission to other MIDlets to access the databases which it creates?

Thanks for the info
