Dear java.help:
I just started learning java and was trying to compile some java sourc
from the Javascript World Submission webpage. I know I have loaded m
JDK successfully since I can compile other examples but when I try t
compile the following code, I get several errors.
I typed "javac J1.java(source file name)"
Any feedback is appreciated.
thanks
Banjo
