Java Servlets,loaded via the Class.forName() method. We also saw how this is exploited for applets. When an applet class is found embedded in an HTML document, its corresponding .class files are retrieved from the Web server and loaded into a typical Java-enabled host browser.

Object Serialization and Remote Method Invocation,a. However, databases are not typically used to store objects, particularly Java objects. On the other hand, flat files alone do not cope well with object structure. What is required is some means to preserve the state of a Java object so that it may be easily stored and subsequently restored to its original state.

Introduction,Object-oriented programming has been in practice for many years now. While the fundamental object-oriented concepts were first introduced via the class construct in the Simula programming language in the 1960s, the programming technique was only accepted with the advent of Smalltalk-80 more than a decade later.

Implementation in Java,In Chapter 3, we demonstrated how object-oriented concepts can be implemented via notations in the Java programming language. For validation purposes, these concepts allow objects in our system to be operational. We now proceed to see how they are practically applied to example problems as typical programs.

Modularity,We have so far discussed the basic facilities for creating objects through Java class definitions and code reuse by inheriting properties of similar but more general classes. In this chapter, we look at the important issue of modularity and the related mechanisms available in Java.

Input and Output Operations,We have covered all the basic mechanisms of Java, but not much has been said about input and output operations such as reading from and writing to files. In fact, the Java programming language excludes any description of performing such operations. Instead, this critical functionality is implemented by standard libraries.

A Quick Tour of Java,this chapter, we see how the Java programming language is used to construct our object model of the problem domain. This approach is advantageous in that it allows our model to operate or “come alive” under computer control.
