This Java language was created in June 1991 for interactive television but the product was too advanced for the cabel TV in that time. The SUN Microsystems released Java version 1.0 for public use in 1995 and the purpose was to programm once and use the code in every platform. Later on the Java was take over by Oracle. The company has been using the Java platform among with it’s many products like Oracle Forms etc. The main reason of programming Java is for reason that your programm can be run with Linux, Unix or Windows platforms without re-writing the code.
To start the Java learning course you will need the Java platform. The good news is it is for free and you can just download and install into your computer. When you are using Linux or Unix systems there will be an option to download and install via package maintenance tool or you can go to the website is www.java.com and do the same manually (see the picture below). Windows users need to download and install manually the platform and you can find the file from the same webpage.
Now the second tool is an optional choice but by our opinion it makes your life easier and the Java code would be better to read. But as we said you can do all of it with Notepad or Gedit text editor tools and the output is the same. In this course we will use the Eclipse program to do through the Java examples. The program is free and available your Linux or Unix package manager and as well on website www.eclipse.org. Once sorry for Windows users but you need to download and install the platform from the same link. The program looks on opening as the following picture.
And on first time you’ll see the welcome window. There you can find some existing samples and tutorial.
Now you got all you will need to start our Java tutorial and on the next page you can write your first Java program.
