Do I have to download a package and place it in my C:/ before importing it?
Hi Javaprogrammers,
I am trying to test out an exercise in my beginner's book, Big Java. They have an example where they import javax.swing.Jframe and other class such as RectangleViewer. I also want to import java.awt.Graphics.... as well as the Rectangle, and the Graphics2D
Are these in the preexisting packages? Or do I have to find awt online and download it and place it in the java folder or something? Thanks for any pointers in advance.
Sincerely,
Rosalind

These ones are preexisting. If the package starts with java or javax, it is *usually* a package already built-in. That is not necessarily *always* the case, since 3rd party developers could start their package with java or javax, but I have never personally seen anyone do that.

Re: Do I have to download a package and place it in my C:/ before importing it?
You sometimes hear the term "Java Core API" or "Java SE", SE = Standard Edition, to describe the libraries or packages that come included with Java's SDK. If you look at the main API page (the link happens to be to Java 7), you can scroll through all of the included packages in the upper left portion of the page, select one (like javax.swing for example), and then see the classes included in that package in the bottom left portion of the page, including JFrame (which you listed incorrectly - remember that Java is VERY case sensitive). If you scroll through the whole package list, you'll see they all start with either java, javax, or org.
I doubt you will have to download any 3rd party libraries to do the work in the book you have, although it would be a good lesson to teach you someday.
