No matter what type of business you’re in, boosting your bottom line is always in the back of your mind. In a rough economy, it can be tempting to focus too much on pulling in more money and not enough on containing it from within.
That’s right, containing it. You have the potential to lose hundreds of thousands of dollars every year right under your nose from something as simple as lack of or ineffective computer training.
How much do the employees you have working for you right now really understand about technology? How good is your IT tech department? Technology changes faster than a blink of an eye and oftentimes, businesses struggle to keep their top employees trained.
With millions of dollars being lost to Internet espionage, file corruption and other computer crimes, staying on top of changes is essential. Recently, online learning centers have been emerging as the go-to method for quick and inexpensive learning. Unfortunately, this type of computer learning isn’t always the best solution.
Since its foundation, HSG has been a leader in Business Rule Management Systems Training and Consulting services by way of the Blaze Advisor Rule Engine. Over the years we have provided such services to many of the worlds largest corporations and government institutions whose respective backgrounds include credit card processing, banking, insurance, health and medicine and more, much more. Such training and consulting services have included:
Create a wrapper object model in either Java, .NET or XML
Identify and catalog business rules
Develop a rule architecture within Blaze Advisor that isolates rule repositories as they relate to functionality and corporate policies
Configure, develop and implement a variety of interfaces to the rule engine from disparate systems ranging from mainframe applications written in Cobol to UNIX/Windows applications using Enterprise Java Beans, Windows Services, Web Services, Fat Clients, Java Messaging Services and Web Applications.
Review and update code to boost efficiency either by way of
Removing functions calls within conditional statements
Ensuring that database calls are essential or can be rearchitected in some other manner
Employing the rete algorithm where necessary
Paring down extensively large class models
Deploying such appliations in multi-threaded systems

As part of our Java Tutorials program, we will list a number of interview questions to aid in a better understaing of Java and J2EE and, hopefully, provide a greater likelihood of getting a job. Let us begin with the basics:
1. What is meant by J2EE?
J2EE is an abreviation for Java 2 Platform Enterprise Edition
2. What is the purpose of J2EE?
The purpose of J2EE is to provide a component based platform in a multitier application model with transaction management, web services and reusable component support.
3. What is the tier structure of the typical J2EE application?
A typical J2EE application consists of the following tiers/machines: the client machine (browser/non-browser application), the J2EE server (an application server such as Oracle, JBoss, GlassFish, Tomcat) and a database.
The importance of variables in any programming language can’t be emphasised enough. Even if you are a novice, the chances are good that you will have been using variables for quite a while now.
They are the cornerstone of any language and without them we would not be able to accomplish much of anything. However, most of you up until this point have probably only been working with standard variables, variables which can hold single values such as an integer, a single character, or a string of text.
In this tutorial we are going to take a look at a more special type of variable called an array. Arrays can seem quite daunting at first glance but once you get used to working with them you will wonder how you ever managed to program without them.
The reason arrays are special is because they can hold more than one value. Think about this: say you create a variable which contains a line of text like the code below:
