In summary, if you are looking for a development kit for Java that can compile and run code, you have a few options. You could consider using the Processing IDE, which allows you to code in Java and also includes interactive graphics. Alternatively, you could download Netbeans or Eclipse, both of which come with Java embedded and offer more features for full application projects. Another option is to download the JDK from Oracle and use your platform's editor, though it may be beneficial to have a syntax colorizing editor familiar with Java structure and keywords. If you are having trouble, make sure you have downloaded the correct version for your platform.

I'm using Windows 8 and I have Notepad++ for coding in Java but I need a development kit for Java that can compile and run Java. I went to the website java.sun.com to download J2SE but it doesn't work.

The short answer is you could consider the Processing IDE. It allows you to code in Java within a context of doing interactive graphics. I think it comes with Java embedded.

The long answer would be to download Netbeans or eclipse which come with Java embedded inside and allow you to do full application projects. These are the tools that professional programmers use for development. The IDE editor will do code completion, colorize, look up api and a lot of other features.

The economical answer is to download the JDK from Oracle and install it and use your platform editor. However it really helps to have a syntax colorizing editor familiar with Java structure and keywords.
