Not sure what you're not understanding Imports are used to specify packages/classes that the current class uses. In your case, it looks like it's importing a lot of JFreeChart stuff - which is appropriate because it's a JFreeChart demo. If you need help with the classes that are being imported, you can find JavaDocs for these classes on the JFreeChart website.
