Hi Jim and others, I had computer problems and now have a loaner machine. I don't know if this is the book mentioned earlier, but I am using "Sun Certified Programmer for Java 6 Study Guide," written by Kathy Sierra and Bert Bates. I have the C D and it is very easy to read with Adobe. A friend of mine let me use his C D so I didn't even have to buy the book. Everything including the test at the end of each chapter is accessible. Susie
