Chapter 4. Object Basics and Simple Data Objects

http://java.sun.com/docs/books/tutorial/java/data/index.html

This chapter begins with a general discussion about the life cycle of objects. The information presented applies to objects of all types and includes how to create an object, how to use it, and, finally, how the system cleans up the object when it's no longer being used.

Next, this chapter shows you how to use objects of the following types. Classes for these objects are provided by the Java platform.

  • Character data -either a single character or a series of characters -can be stored and manipulated by one of three classes in java.lang : Character , String , and StringBuffer .

  • To work with numeric data, you use the number classes. The Number class is the superclass for all number classes in the Java platform. Its subclasses include Float , Integer , and so on.

  • You can group values of the same type within arrays. Arrays are supported directly by the Java programming language; there is no array class. Arrays are implicit extensions of the Object class, so you can assign an array to a variable whose type is declared as Object .

The Java platform groups its classes into functional packages. Instead of writing your own classes, you can use one provided by the platform. Most of the classes discussed in this chapter are members of the java.lang package. [1] All the classes in the java.lang package are available to your programs automatically.
