• You can see slides on primitives , as well as this good article .
• Read this article to learn about autoboxing primitives in Java
• Here is a good lecture about classes and objects
• Read carefully this material: Java Philosophy

Here are two more links: about OOP and about names and packages . Do not sit here for a long time, just look.
