So I have literally just started reading the book, and I am stuck at the first lesson. The lesson has you create a small applet (if that's the right term) that acts as a party invitation. The problem that I am having is that the compiler is returning 'Symbol Not Found Error' on things such as capital letters, and even periods.

My code (copied directly from the book, line for line)


And the compiling error

If someone could explain what is happening (with some detail, I'm a beginner remember ;) ) and what I could do to fix it, I would greatly appreciate it.

Bryce, Welcome to Ranch

You have imported the packages incorrectly. It should have been

If you need to import only a single class from a package then it would be written like this



Here only the Frame class would be imported from awt package

Welcome to the Ranch

Beware of the Party example from HFJ; it is incomplete and cannot be executed in its current form. It is usually considered better form to list all the classes you are importing, even if you have several lines starting
import foo.bar.…
