• Read about the if-else construct .
• On primitives, you can see the slides , as well as this good article .
• Read this article to learn about autopacking primitives in Java
• Here is a good lecture about classes and objects
• Read this material carefully: Java Philosophy

Here are two more links: about OOP and about names and packages . Don’t sit here for a long time, just look through it.
