Chapter 2 - java classes and information hiding page 1. Chapter 2 - java classes and information hiding page 2. Chapter 2 - java classes and information hiding page 3. In java, object-oriented programming (oop) is supported by implementing classes. Each class defines a collection of data, called its instance variables. In addition, a class has the ability to include two other items: constructors and methods. Constructors are designed to provide initial values to the class"s data; methods are designed to manipulate the data. Taken together, the instance variables, constructors, and methods of a class are called the class members. We generally use private instance variables and public methods. This approach supports information hiding by forbidding data components of a class to be directly accessed outside of the class. A new class can be implemented in a java package that is provided to other programmers to use.
