Java Programming Training Classes in Washington D C, Virginia
Training Suggestions from the Experts

An Experienced Java developer must know
... everything or so it can seem. A solid grasp and knowledge of Object Oriented Programming constructs such as inheritance, polymorphism, interfaces and reflection are essential. Next in line is the knowldge to be able to import/export file data, running SQL queries, using regular expressions and, possibly, knowing how to write multi-threaded code and make socket connections. A class that addresses most of these topics is: Fast Track to Java 11 and OO Development.
For the more daring Java enthusiast and especially for those looking to become professional Java developers, knowledge of the Spring Framework is expected. A perfect class for this is: Fast Track to Spring Framework and Spring MVC/Rest. Not only does this course provide students with a great introduction to spring, it goes beyond the basics with a solid delve into Spring and web development.
Another consideration is learning JBoss aka Wildfly, the free Application Server from RedHat. JBoss has become the workhorse of most Java EE applications. Add to that a class on Tomcat, the defacto servlet engine, and the student can be considered 'ready' for employment.

Blog Entries publications that: entertain, make you think, offer insight
It’s the eternal conundrum of a hiring manager – you have to hire for every single position in the company without any first-hand experience. How to do it? If you can have a trusted programmer sit in on the interview, that’s ideal, of course. But what if you’re hiring your first programmer? Or what if you’re hiring a freelancer? Or what if company policy dictates that you’re the only person allowed to do the interviewing? Well, in that case, you need some helpful advice and your innate bullshit detector. We questioned programmers and hiring managers and compiled a list of dos and don’ts. Here are some things to ask when interviewing programmers:
Past Experience
Ask the programmer about the biggest disaster of his career so far, and how he handled it. Did he come in at midnight to fix the code? Was he unaware of the problem until someone brought it up? Did someone else handle it? According to our programmer sources, “Anyone worth their salt has caused a major meltdown. If they say they haven’t, they’re lying. Or very, very green.” Pushing a code with bugs in it isn’t necessarily bad. Not handling it well is bad.
As usual, your biggest asset is not knowing the field, it is knowing people. Asking about career disasters can be uncomfortable, but if the interviewee is experienced and honest then she won’t have a problem telling you about it, and you will get an idea of how she handles mishaps. Even if you don’t understand what the disaster was or how it was fixed, you should be able to tell how honest she’s being and how she handles being put on the spot.
Every programming language has a mechanism to allow the programmer to create variables which hold custom data entered in by either the coder themselves or by the user of the application.
Regardless of whether you’re new to programming or not, you will have used variables and you should understand that in javascript they can hold any value such as a number or a string of text.
There is also another type of variable called an Array. Now, depending on who you talk to, some will say an array is actually an object, while others say it is a variable. Neither one is wrong but for the sake of simplicity we’ll refer to it as a variable.
Now, arrays are special because they can hold multiple values as opposed to standard variables which can only hold a single value at one time. If you can, try and imagine that your computer’s memory is made up of thousands of little boxes, and each of those boxes has an address which javascript will use to retrieve the array values when needed.
Back in the late 90's, there were a number of computer scienctists claiming to know java in hopes of landing a job for $80k+/year. In fact, I know a woman you did just that: land a project management position with a large telecom and have no experience whatsoever. I guess the company figured that some talent was better than no talent and that, with some time and training, she would be productive. Like all gravey train stories, that one, too, had an end. After only a year, she was given a pink slip.
Not only are those days over, job prospects for the IT professional have become considerably more demanding. Saying you know java today is like saying you know that you have expertise with the computer mouse; that's nice, but what else can you do. This demand can be attributed to an increase in global competition along with the introduction of a number of varied technologies. Take .NET, Python, Ruby, Spring, Hibernate ... as an example; most of them, along with many others, are the backbone of the IT infrastructure of most mid-to-large scale US corporations. Imagine the difficulty in finding the right mix of experience, knowledge and talent to support, maintain and devlop with such desparate technologies.
Well imagine no more. According to the IT Hiring Index and Skills Report, seventy percent of CIO’s said it's challenging to find skilled professionals today. If we add the rapid rate of technological innovation into the mix of factors affecting more businesses now than ever before, it’s understandable that the skill gap is widening. Consider this as well: the economic downturn has forced many potential retires to remain in the workforce. This is detailed in MetLife's annual Study of Employee Benefits which states that“more than one-third of surveyed Baby Boomers (35%) say that as a result of economic conditions they plan to postpone their retirement.” How then does the corporation hire new, more informed/better educated talent? Indeed, the IT skills gap is ever widening.
In order to compensate for these skill discrepencies, many firms have resorted to hire the ideal candidates by demanding they possess a christmas wish list of expertise in a variety of different IT disciplines. It would not be uncommon that such individuals have a strong programming background and are brilliant DBA's. What about training? That is certainly a way to diminish the skills gap.
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.
