Classes are an integral part of Object Orientation, encapsulating state and behavior for each component in a larger system, thereby allowing us to express our software in terms of the structures and relationships which link its autonomous component parts.
JDM aims at building a standard API for data mining with the goal that client applications coded to the specification are not dependent on any specific vendor application. The JDBC specification provides a good analogy to the potential of JDM.
A programmer can be significantly more productive in Python than in Java. How much more productive? The most widely accepted estimate is 5-10 times. On the basis of my own personal experience with the two languages, I agree with this estimate.
The Java API for XML Processing (JAXP) lets you validate, parse, and transform XML using several different APIs. JAXP provides both ease of use and vendor neutrality. This article, the first of a two-part series introducing JAXP, shows you how to take advantage of the API’s parsing and validation features. Part 2 will cover XSL transformations using JAXP.
When you have a hammer, everything looks like a nail (as the old saying goes). But what if you don’t have a hammer? Well, sometimes, you can borrow a hammer. Then, hammer in hand, you can bang the virtual nails with the borrowed hammer, return it, and no one is the wiser. In this month’s Java theory and practice, Brian Goetz demonstrates how data manipulation hammers such as SQL or XQuery can be applied to ad-hoc data.
Reduce the number of database hits and improve your Web application’s efficiency when you load common shared list values only once. In this code-filled article, learn to load the values for drop-down lists when your Web application starts and then to share these loaded list values among all the users of your application.
This article explains how to implement session tracking using two of the simplest & oldest methods available to programmers. The techniques presented in this article use some old, tried and tested ways which are extremely popular even today. After reading this article you would be able to implement session tracking using any language.
This is actually a piece of code used by me to access XML files through Java. I have added some explanation. In case you are interested in knowing how to access XML files using Java, quickly without reading a lot of material, this is the right article for you.
AspectJ is an aspect-oriented extension of the Java™ language that enables a modular implementation of crosscutting concerns. This crosscutting behavior, which can be static or dynamic, presents an extra challenge to tools that support AspectJ. The AJDT project aims to provide Eclipse platform-based tools for AspectJ, consistent with the Eclipse Java Development Tools (JDT), with additional capabilities for visualizing and understanding the crosscutting nature of aspect-oriented applications.
