It means that either there is a problem in your Java source code, or there is a problem in the way that you are compiling it.

How ya doin?"); scc.p("Connected1 "); scc.p("Connected2 "); String a=scc.is; double b=scc.id; int c=scc.ii; scc.pl (a); scc.pl (b); scc.pl (c); } } and it gives me the following Error: "cannot find symbol- variable is What am I doing wrong? How can i fix this? Thanks in ahead! * Edit: Thank you so much for the answer! so i fixed it, and ran into another problem... I can not print out b or c because the print i wrote requires a String, and b and c can only be double and int, so that won't work. is there any way of changing the print (scc.p and scc.pr) so it will be able to recieve any kind of parameter? thanks! java variables input find symbol share|improve this question edited Nov 28 '12 at 5:04 asked Nov 27 '12 at 18:48 user1857509 613 () is missing. double b=scc.
