Tools you will need:
- For performing the examples discussed in this tutorial, you will need a Pentium 200-MHz computer with a minimum of 64 MB of RAM (128 MB of RAM recommended).
- Linux 7.1 or Windows xp/7/8 operating system.

Local Environment Setup
Java SE is freely available from the link Download Java. So you download a version based on your operating system.
Follow the instructions to download java and run the .exe to install Java on your machine. Once you installed Java on your machine, you would need to set environment variables to point to correct installation directories.
Setting up the path for windows:
Assuming you have installed Java in C:\Program Files\java\jdk directory:
- Right-click on 'My Computer' and select 'Properties'.
- Click on the 'Environment variables' button under the 'Advanced' tab.
- Now, alter the 'Path' variable so that it also contains the path to the Java executable.
Example, if the path is currently set to 'C:\WINDOWS\SYSTEM32', then change your path to read 'C:\WINDOWS\SYSTEM32;c:\Program Files\java\jdk\bin'.
To write your Java programs, you will need a text editor. There are even more sophisticated IDEs available in the market. But for now, you can consider one of the following:
- Notepad: On Windows machine you can use any simple text editor like Notepad (Recommended for this tutorial), TextPad.
- Netbeans: is a Java IDE that is open-source and free which can be downloaded from http://www.netbeans.org/index.html.
- Eclipse: is also a Java IDE developed by the eclipse open-source community and can be downloaded from http://www.eclipse.org/.
