COMPILED javac AbstractClock.java with no errors.

I am running this in commandprompt in Windows. I have seen other posts and changed classpath and run command, but still error occurs.Please provide steps suitable for running in windows in command prompt to rectify this mistake.
Is you java file in C:\Users\Neeraj\Prg or is it in C:\Users\Neeraj\Prg\net\sf\fmj\ejmf\toolkit\media\ ?
ReplyDeletePackages in java are related to directories. So your classpath is the top level directory in which packages live. A class with the package name net.sf.fmj.ejmf.toolkit should be in that directory.
Since javax.media package was needed, i installed the same. I think Maybe net.sf.fmj.ejmf.toolkit package is present in javax.media.
ReplyDeleteProgram files has JAVA and JMF directories.So should i include both in the classpath.
