Re: Compile java files in packages

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
