What Makes Java Different From Other Programming Languages?

On several levels, Java is different than other programming languages. For potential developers, these differences provide several unique challenges. To meet these challenges, a niche employment market has arisen to provide skilled programmers who understand the Java development kit. In particular, the cross-platform capabilities of the language have created a demand for a class of programmers who can write with a large base of end users in mind.

Sun Microsystem's flagship programming environment has long be associated with embedded web software. However, this doesn't mean that there isn't a need for regular applications as well. In fact, there is graphical user interface toolkit called Swing that tries to emulate several different operating systems. Java is said to be the "write once and run anywhere" development architecture, so this sort of cross-platform technology is particularly important. Individuals who want to find a job in the world of Java might be able to carve out their own niche in Swing development.

Other firms might want to hire based on knowledge of the Abstract Window Toolkit. This is an alternative to Swing, and tries to emulate the operating system that is currently being run. This is a marked difference from Swing GUI architecture, since an application written in Swing will generally look the same regardless of the type of operating system it's being run on. Since it preserves the look and feel of the type of system software being used, some developers prefer to use this method. Of course, potential job applicants who have experience working with both of these two toolkits will have a leg up on the competition.

With the rapid growth of mobile devices, Java ME is on the rise. This is a version of the platform for use in embedded devices. Programmers with experience in working with this system might have an edge, because it's such a standard system for these kinds of architectures. However, some developers are starting to consider the system to be old news. Nevertheless, even these firms might want to hire developers with experience in Java as well as another system. As people turn towards Google Android or Windows Phone 7 as their marketing platform, they will surely still want to be able to sell products to the worldwide users of over 2 billion Java Me devices-

We live in a digital era where the role that Java (and others) play is increasing and becoming more and more important.

Becoming a Professional Hacker - Are Programming Skills Really Necessary?

This is one of the most frequently asked questions about the world of ethical hacking. Do you need to learn how to program to become an penetration tester? My answer would be "You are NOT going to be a good hacker."

Ethical Hacking is a loophole for us to do what we love and actually get paid to do it. Every hacker I have ever talked to got their start with an intense curiosity about computers, networks, etc. and how they all work together. Programming languages allow us to create anything we can imagine. If I was an architect, I could design any shape building I wanted, BUT it had to adhere to the laws of physics so that it was structurally sound. In programming, there are NO laws. ANYTHING can be created.

When I got my start in computers, I took every programming class I could. Read every single book I could. I became obsessed with all that could be done on a computer. Programming skills are what set apart real computer gurus and the script kiddies who just run programs (they didn't write themselves) to wreak havoc.

There are plenty of topics within Ethical Hacking that require no programming skills whatsoever. But if you truly are looking into a career as an Ethical Hacker, you are like me and want to learn as much as you can about everything computing. There are hundreds of programming languages to choose from compiled languages like C to scripting languages like Python and Ruby that are interpreted on the spot. Occasionally, I will even dive deeper and play around with esoteric languages such as Befunge where the whole point of the language is to be completely obfuscated. It turns programming even the simplest of programs into a mind challenging puzzle.

Whatever your interest is, programming languages are necessary for a fuller understanding of how computers work, process things, and communicate with eachother. The next important question is: Which programming languages should I learn to stay competitive?

The answer to this will vary from programmer to programmer. My advice is to learn a language or two from each category. You'll begin to find that most programming languages work similarly but with varied syntax.

Starting off, I would recommend the way I started my programming career, with Java. It is an extremely powerful Object Oriented programming language and is widely used in today's world.

If you're beginning to feel comfortable with Java, I would suggest stepping it up and trying to tackle C++ or get down even closer to machine code with C.

Scripting languages are becoming extremely popular and are definitely worth looking into especially for the aspiring Ethical Hacker. I would mess around with LISP, perl, Ruby, and Python. Find one or two you like that suit your needs and master them. Each one has its advantages.

There is unlimited information online to learn any of these languages and get started on your journey to an exciting career as an Ethical Hacker.
