Java how to add a library or API while compiling with command line?

Question

The question says it all, I am trying to use an external library in my code, but it tells me that the packages I referenced to don't exist so I'm guessing the imports don't work. How do I do this?

Use the -cp option as described in the javac notes.

Specify where to find user class files, and (optionally) annotation processors and source files. This class path overrides the user class path in the CLASSPATH environment variable. If neither CLASSPATH, -cp nor -classpath is specified, the user class path consists of the current directory. ..
