Keyword used to indicate the declaration of a class. A class is a composite of data and methods (functions) which may be instantiated as objects. The first letter of a class name is usually uppercase to separate it from other kinds of variables. A related tutorial on <a href="http://java.sun.com/docs/books/tutorial/java/concepts/index.html" target="_blank">Object-Oriented Programming</a> is hosted from the Sun website.
