Nice to meet you. There are a couple of good places to start to learn about the basics of Java. You have "The Java Tutorial"
which is a source driectly from the creators of Java i.e. formerly Sun Microsystems now Oracle. I have also been suggesting reading the book "Beginning Java Objects" second edition book. This deals with programming from an object modeling viewpoint. It might also be worth looking at the Deitel Series of books - Java: How To Program. Good luck in your studies and feel free to add me as a friend.
