Java - How do I use a class file?
You have to import by calling the name of source package . ie import hello.Car;
. In your case you are trying to call import on JAR folder name which leads to an error "cannot find symbol" .
Let me try to give an example for better understandability
Consider this simple Vehicle application which has Car class and Test Car class
Convert it into jar and add it into another project called ImportVehicleJar

Hope this helps !!
In Netbeans (version 5.5.1), you can add a jar file to a project by right clicking the project name, and choosing Properties, then Libraries (from Categories), and there is an "Add JAR/Folder" button, which can be used for adding it to the compile-time and/or run-time classpath. Adding it to the Compile-time Libraries is well enough, because it will automatically added to the run-time through its "Classpath for Compiling Sources" entry.
