Basics/PreLims of JAVA Programming

Introduction

Since the time of COBOL & FORTRAN, new programming languages have been invented and developed. C, which was very popular when it came out, did not incorporate the ideas of OOP (Object Oriented Programming). Then, came Bjarne Straustrap, who created C++, which had the ideas of C, but incorported C++.

In the 90's, a company named Sun Microsystems released Java. What made Java so unique? Mainly that it was platform independent, meaning you could take a program made in Windows and run it on Linux, Mac, etc. (software independent), and you could move it around with different types of hardware, and it would still function correctly.

In this article, I will not get into how to start programming in Java. That will be a different FAQ. I will teach you the run down on how Java works and how to get it going.

The General Operating Sequence of Java

In Java, you have your Source Code, which is what you enter into your IDE (Integrated Development Environment, this will be discussed later.) Then, the Java compiler named javac.exe will convert the source code into Byte Code. After you compile your code, a .class version of your file will appear. (.class is the extension for the byte code file) Then, the Java executer java.exe will execute the byte code file. That is the run down on how Java operates.

Software Needed to Run Java

First of all, you need Sun's JDK (Java Development Kit) software. You can download this at https://jsecom15k.sun.com/ECom/EComActionSe...49F89FB23EBAF94. You have a choice between an online or offline installation. The online installation file is extremely small compared to the offline installation. The difference? The offline installation means you can run Java apps without access to the internet. If you choose the online installation, you need the internet connected to compile, execute, etc. Java applications.

Run the setup file and install it.

Then, you need an IDE (Integrated Development Environment). An IDE integrates a notepad-like interface and access the Java compiler & executer much easier. Otherwise, you would have to use Notepad and Command prompt.

A free IDE is always good and the one I personally prefer and use is JCreator. You can download it from http://www.jcreator.com. The Professional version has much more features for the professional programmers, but for beginners and home programmers, Basic LE version is fine.

Once you install this IDE, you can start programming in Java. Later, I will write another FAQ on how to write Java applets, etc.

You posted the comment, that's why I asked you to search boy.

I never called you by personal search boy. You need to calm down RagingFuryBlack. Don't come here with such an argumentative attitude.

He doesnt need to calm down, he was joking. You need to take stuff less seriously.

What are you? His personal guardian?

The reason I took it seriously is because he has posted like this other time.

And you're pretty stupid for not reading the topic title and the article.

So, learn to read before you criticize someone else.

No, it does not.

What would you rather use? C++?

Or even better...Assembly? ^o) :wub:
