To execute an executable from java use the Process and Runtime classes.
How to pass data between the two???
One way would be to could use Sockets.

Something like this you have to do.

Process p = Runtime.getRuntime().exec(path_to_executable_file);

Something like this you have to do.

Process p = Runtime.getRuntime().exec(path_to_executable_file);

of course you do that also with try and catch statement,cuz the excpetion can be thrown

Definitely you must handle exception on each step. Not only in this case, each time when you deal with programming it must. A quality product can never clash because of an unhandle exception. Actually in Java it's not a big issue, but in low level languages like C++ you are dead.
