Here are the instructions for downloading JDK (Java Development Kit) and the JCreator IDE (Integrated Development Environment). You may prefer to download JDK as a step in the downloading of JCreator. Both of these programs are free.

The JDK bundle, also called the Java SE (Standard Edition) contains among other things, the java compiler (javac) which produces java bytecode. It also contains the Java Virtual Machine (JVM) which executes the bytecode, i.e., runsinterprets the java byte code for your platform

We say that JCreator is a "thin layer" above the JDK. This means that it does not contain the compiler or the interpreter (it points to JDK); but it will enable you to compile, debug and run your programs by chosing menu options. For instance, if you make a compilation error, JCreator displays the error messages in a separate window. When you double click a given error message, JCreator will point to the offending line in your program. This is very helpful, especially for long programs.

Both of these programs are downloaded in zipped form. In order to unzip them you need WINZIP. If you don't have it, download it from http://www.winzip.com/downauto.cgi?winzip80.exe.
