How To Java (English and German)

There are several coding lenguages you problably heard of.

f.e. Java, Java Script, Objective-C, C++, (Visual) Basic, PHP, Python...

In this or some other way all coding lenguages resemble. Codes tells the computer what to do. You can say that you give the computer a desired duty/ task/ function/ mission/ assignment.

For the manifold needs in the computer world requires a suitable walktrough for every technical solution. While C/C++ suits better for rudimental hardware in a computer (proccessing Unit and so on), Java is more pratical for user interfaced software, desktop applications (a.s.o.). At this point I won't explain in detail why we distinguish programming lenguages, but each lenguages got its own advantages.

You won't cut a tree with a pickaxe.

It's really easy to learn Java and it is my pleassure to tell you how you'll achieve that. You don't have to be an absolute crack or nerd to be good in coding. For sure it takes some time and patience, but that's pretty much all it takes. You'll have a nice reputation afterwards and you'll be able to participate in nice communal projects and earn easy money with it (maintenance of online databases, coding your own computer games a. s. o.). To sum it all up:

The possiblities are infinite and limitless.

Let's get started!

Everything you'll learn in the next minutes won't stay more than 2 minutes in your memory if you not practice it 15 times 15 Minutes. So take it serious and calculate at least 15 minutes per day. It's obligatory.

Please downlaod one of the free PDFs about Java-Coding. Those are well written HowToJavaPDFs and introduce you really nice to Java. For now:

For all german readers: https://www.uni-trier.de/fileadmin/urt/doku/java/v70/Java7.pdf

For all english readers: http://www.oracle.com/events/global/en/java-outreach/resources/java-a-beginners-guide-1720064.pdf

TASK NUMBER 1 (german readers only): Please read the pages 1 to 22 and answer all the questions on page 22.

TASK NUMBER 1 (english readers only): Please read the pages 1 to 30 and answer all the questions on page 30.

Now you can Install our Eclipse. An OpenSource Editor for Java Coding. Get the latest version of Eclipse at this link and install it: https://eclipse.org/home/index.php

TASK NUMBER 2 (german readers only): Read the second chapter of the Java7.pdf and try to get familiar with eclipse by creating a
(1)new project (name it MyFirstProject),
(2)a new class in this project (named HelloWorld) and
(3) put the following code in and
(4) test your programm by running the console.

public class HelloWorld
{
public static void main (String[] args) {
System.out.println("Hello World!");
}
}

TASK NUMBER 2 (english readers only): Watch this video ->

}
}

Congratulations!

You appropriate some of the basics, learned the origin of Java and wrote your first java programm. Don't get me wrong but you're not that far away from mastering Java. That's all I want you to teach for now and I hope you got a first glance of coding. I'm going to teach you more Java in the upcoming post.

If you're not willing to learn, no one can help you. If you are determined to learn, no one can stop you.

If you want to learn more about computing and informatics I recommend you this PDF here:
