So learning the Head First way is more important than ever. If you've read a Head First book, you know what to expect--a visually rich format designed for the way your brain works.

If you haven't, you're in for a treat. You'll see why people say it's unlike any other Java book you've ever read.

By exploiting how your brain works, Head First Java compresses the time it takes to learn and retain--complex information. Its unique approach not only shows you what you need to know about Java syntax, it teaches you to think like a Java programmer. Who got the chair? When you design a class, think about the objects that will be created from that class type.

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.

That means pass-by-copy Cool things you can do with parameters and return types Encapsulation Do it or risk humiliation and ridicule Hide the data Encapsulating the GoodDog class How do objects in an array behave? Declaring and initializing instance variables The difference between instance and local variables Comparing variables primitives or references 5.

Writing a Program: A bug? A different game interaction More about for loops Regular non-enhanced for loops Trips through a loop Difference between for and while The enhanced for loop Casting primitives 6.

See a Problem?

Inheritance and Polymorphism: Understanding Inheritance An inheritance example: Which methods should we override? Looking for more inheritance opportunities Which method is called? Who gets the Porsche, who gets the porcelain?

When designing with inheritance, are you using or abusing? So what does all this inheritance really download you?

Inheritance lets you guarantee that all classes grouped under a certain supertype have all the methods that the supertype has. Interfaces and Abstract Classes: Serious Polymorphism Did we forget about something when we designed this? Why not make a class generic enough to take anything?

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?

Try asking the "doctor" on page , who inherited his knowledge so he didn't have to go to medical school. Passing by copy instead of value?

Let the depressed office worker making multiple photocopies of his face help you remember which is which. And, of course, there's the ever-present crossword puzzles that I even find my wife penciling words on in her spare time.

There's plenty of J2SE 5. For example, number formatting—familiar to anyone who has programmed using the old printf functions in C—gets due coverage in Chapter The enhanced for loop gets some text on page , and the all important generics in this case, with the Collections framework gets a thorough treatment in Chapter Even the Java language itself on page 4 has morphed from a turtle Java 1.
