- Jac Wright » An Introduction to Object-Oriented Programming (1 of 5)
This is the first of five articles on object oriented-programming. * An Introduction to Object-Oriented Programming * Thinking Object-Oriented * Planning an Application * Creating Objects * Making Objects Reusable An Introduction to Object-Oriented Programming will give a brief overview of why there is such a thing as object-oriented programming. Conceptualizing Systems will help us to better picture a system in terms of objects and how the relate to each other. Planning an Application will teach us the importance of planning and what we should do to plan. Creating Objects explains how the objects in our application are born, and how they should be structured. Making Objects Reusable covers some more advanced topics and allows us to reus

- Java 101: What if I Don't Know Java?
Today, more and more languages have the same concepts, control structures, and even syntax. If you're new to the world of object oriented programming, though, there are a few "gotchas" you should be aware of. For the most part, WebLogic Workshop hides most of these details from you - letting you focus on the procedural business logic that really matters - but its always good to be aware of some of the details. This section outlines the basic rules of Java syntax and gives a brief introduction to some of the Java concepts that will be important for you to be familiar with as a WebLogic Workshop developer. For a more detailed and thorough introduction to the language, we've recommended several books and introductory courses that will help you get started.

- Java Practices: Recursive file listing
The File class has methods for listing the contents of a single directory, such as list and listFiles, but there is no method for listing all files in a directory tree. Here is a simple utility which returns a sorted List of File objects which reside under a given root directory. It uses recursion. import java.util.*; import java.io.*; /** * @author javapractices.com * @author Alex Wong */ public final class FileListing { /** * Demonstrate use. */ public static void main(String... aArguments) throws FileNotFoundException { File tempDir = new File(aArguments[0]); List files = FileListing.getFileListing( tempDir );

- Java Tutorial 15 - Graphics and Imaging
Graphics brings life to applications. Java allows creation and modification of images using both awt and the newer JFC 2D architecture. Artists tend to think in terms of canvas as the foundation for their images and graphics. Swing JPanel and awt Canvas class objects can be used as the basic canvas. Java applets or applications tie these canvases to their window frames. All output to the canvas takes place through a graphics context encapsulated by the Graphics class. This tutorial introduces some fundamental concepts of graphics and imaging.
Covers multithreading, daemon threads,object stream serialization and transients. Topics: the Thread class,timeslicing, assigning priority, the event dispatch thread,synchronization, starvation and deadlock. Examples: digital clocks,splash screens, animation, piped streams and object stream serialization
- Java Tutorial: Applets
In this section of the tutorial, we are going to create a basic applet for a web browser. First of all, a class must be defined that inherits from the class java.applet.Applet. The Applet class is the standard class inherited for writing applets. It contains the methods to paint to the screen and create the window. The inherited class must be declared public. In this example, we will create an applet that says "Hi, Mom!". Before you start, take a look at what you will be building by executing a finished applet. To return to this section after viewing the applet, use the Back option on your browser. You can see the "Hi Mom!" applet execute by clicking here on hi.applet. The Applet ProgramRAM To create the "Hi, Mom" applet, create (e.g., with a text editor) a
- Java Tutorial: Don't Fear the Oop!
Meet Eunice. Eunice writes Westerns. Her books about life in the American Wild West have become so popular that everybody rushes to buy them. Her readers are never disappointed, because Eunice's books are very consistent. How does she manage this? Well, before Eunice writes anything, she sits down at her desk, sweeps aside the clutter, and places a single piece of paper down on her desk. It is on this one page that she writes her whole story. How can Eunice get the whole story onto one page? Simple. Everything she writes on the page is just a sequence of events, or plot. Setting, character development, and how her characters interact is all taken care of elsewhere. How does she do that? Let's find out. You see, Eunice, more than anything else, is orderly an
