Think about Things an object knows about itself are called Things an object can do are called A class is not an object. Get out of main!
The two uses of main: Primitives and References: Back away from that keyword! Control your Dog with a reference variable What happens if the Dog is in a Dog array? A Dog example 4. Methods Use Instance Variables: How Objects Behave Remember: The size affects the bark You can send things to a method You can get things back from a method You can send more than one thing to a method Calling a two-parameter method, and sending it two arguments You can pass variables into a method, as long as the variable type matches the parameter type Java is pass-by-value.

Using polymorphic references of type Object has a price Making and Implementing the Pet interface 9. Constructors and Garbage Collection: If local variables live on the stack, where do instance variables live? How do you invoke a superclass constructor? Can the child exist before the parents? Superclass constructors with arguments Invoking one overloaded constructor from another Now we know how an object is born, but how long does an object live? What about reference variables?
Numbers and Statics: Static variable: Math methods Wrapping a primitive Before Java 5. Wrappers have static utility methods too! And now in reverse Want to know why inheritance isn't always a good thing?
