Compile java files in packages

Fri Jun 5 11:26:00 GMT 2009

Hi Vaijayanthi Mala Suresh,
Nope, sorry I cant. I haven't use "make" yet. And this maybe the next
step I have to learn.
What I was just doing lately was to compile files by individually,
since I am involved with relatively small number of files.
If you will be able make one, Please share me some samples.
Regards,
ivanceras
