If you are technically minded and you want to learn a new and very valuable skill, you might want to learn Java programming. It’s a coding language which is in huge demand, and powers a lot of the Internet that is obviously one of the most important parts of the economy.
What is Java?
Java is a general-purpose programming language which is easy to use, fun to design, and the whole idea is that it runs on any system in the world.
Why should you learn Java?
Java is used on the Internet, in apps and in computer programs. High level programmers can earn a virtually unlimited salary because of the high demand for Java. Even junior programmers can get an above-average wage in an entry level position. Is also rewarding and challenging, so good for your brain!
What are the key features of Java?
The key feature of Java above all, is that it is designed to run with as few dependencies as possible-what this means is that it is designed with running it on a variety of different systems in mind. Some languages are not like this, and you can only run them on an Apple machine, for instance, or they won’t run on a tablet without extra programs having to be downloaded by the end user.
Java is an object oriented programming language, this is handy because it treats every little bit of code or action as an object. What this means it’s easier to debug, and think conceptually about the program you are writing. Programming is a very abstract skill, so having an object-oriented language is a key to understanding easily and getting started efficiently.
How do I get started?
It’s very easy to get started with Java. There are many resources, a lot of them free and available online, to help you take your first steps. However, we can go one step further in this article and actually show you how to write your first program.
A lot of people are put off by programming, because they see the Facebook’s and Microsoft’s of the world and it all seems so out of reach that people never start. The thing with programming is that it’s just a case of typing and planning. If you can do both of those things, then you can program. And at the beginning, don’t ask too many questions-for instance, follow our easy example just by typing it in. Then you will have completed your first program.
An easy Example:
Simply type out the following –
public class Hello { public static void main(String[] Args) {
System.out.println(“hello there”);
}
}
You’ve written your first Java program without breaking a sweat!
This is a modification of the ever so common “Hello World” program that everyone writes for their first time. If you run this program, it will print on screen the words, “hello there.”
Now that we’ve demystified the experience for you, we hope that you’ll go and start your Java adventure.
