taking input in java when a bluetooth device gets connected

[saqib db]

hi

i am new to this forum and dont know if this is the right section to post it or not, but here is my question.

i am new to java programming and i want to make a software which basically gives some kind of input when a bluetooth device(cellphone) gets connected to pc........

i.e if cell phone #1 gets connected, it gives 1 input in my java code... if cell phone #2 gets connected, it gives 2 input in my java code and so on.........

i dont need communication between cell phone and pc, just a way for connecting and finding which cellphone is connected............


P.S i am using netbeans 7.0.1
