java - Input and output stream using RXTX with button -
first of all, sorry english, it's not mother tongue.
i'm trying make java interface rxtx library communicate serial port. made interface using jigloo (shame on me) because java knowledge limited.
the thing i'm trying send data java electronic board pushing jbutton in java interface. here's problem, don't know how that. read have use inputstream , outputstream supposed put ? should create class or classes ?
here code of java ui:

i think take therxtxsample in link below in order figure out how library works:
http://rxtx.qbang.org/wiki/index.php/two_way_communcation_with_the_serial_port
don´t worry, not difficult. need:
one class handle serial port connection:twowayserialcomm,
another 1 write serial port:serialwriter,
finally (it's not strictly necessary recommended) class make bridge between gui , serial port writer (in other words, controller in mvc model).
so every time press jbutton should call controller method , 1 should figure out that.
