Where can I download Java? SDK or JDK?

Hello!

I have decided to learn java & I want to install Java but don't know the best way, I know I have to download it from sun but I am confused Can someone please guide me step by step for the same? I am confused between SDK & JDK!

Thanks again!

You can download version 1.4 of Java from http://java.sun.com/j2se/1.4/download.html. If you want to be able to write your own Java programs that you can compile and run, then you must download the SDK (Software Developers Kit). If you just want to be able to run a Java program that has already been compiled, then you can get away with just downloading the JRE (Java Runtime Environment). Once you have decided which you need, download either the SDK or the JRE. Choose the download that is most suitable for your operating system.

To create a Java Application, you need the following tools to be install on your computer:

* Java SE Development Kit (JDK) - This is the backbone of Java Technology. It allow developer turn plain Java source code into fully functional Java Application. It also include Java Runtime Environment (JRE), which is a program for computer execute Java Application.
* Install Eclipse SDK - This is one of the best tool where you manage your Java project, write your Java source code and build source code into Java program.

There is a more tradisional command line way of developing Java Applicaiton without using any IDE tools such as Eclipse SDK. Since this tutorial aim at setting up the best development environment for beginners without overwhelming them with huge amount of information

Install Eclipse SDK

Download latest Eclipse SDK from http://www.eclipse.org/downloads/ . Installing Eclipse is very easy. In most cases, unpack the downloaded zip on a disk drive with sufficient free space will do. The following list shows what is required:

* JDK. Which you already installed on the step above.
* Sufficient disk space. 300MB.
* Sufficient RAM. Recommanded at least 512RAM for Developer computer. Best if you got 1024RAM or more.

The JDK is the base package - so includes the base langauge compiler and the base libraries.
The EE SDK is a bunch more libraries and includes reference application servers and that sort of thing.

If you want to do JEE development, you need both. Otherwise, if you want to do regular Java development, get the JDK. If you aren't writing code, the JRE should be plenty.

Hey you need to follow this tutorial I hope this helps you!

The JDK is a subset of what is loosely defined as a Software development kit (SDK) in the general sense. In the descriptions which accompany their recent releases for Java SE, EE, and ME, Sun acknowledge that under their terminology, the JDK forms the subset of the SDK which is responsible for the writing and running of Java programs. The remainder of the SDK is composed of extra software, such as Application Servers, Debuggers, and Documentation.
