Parsing data arduino

can anyone help me to make an arduino serial data parsing program. data from Bluetooth HC 05, and read by Arduino

never used the arduino - ?PC? bluetooth link, no “HC 05” hardware available,
also never play bluetooth into processing ( is that what you want to do? )
but any arduino to processing question ( using USB ) i might can help,
( just now work on UNO / Leonardo / DUE – USB – Processing 3.5.3 scope code )

so if you are willing to separate the job into 2
-a- USB connected communication
-b- bluetooth wireless
( just change in Processing the COM port number on your ?laptop? )
start with the questions
