yes it is, Sun has released the code under GPL2
The JRE and the SDK can both be downloaded for free for most platforms. Good IDEs like Eclipse and Netbeans are available for free.
So Java is free and open source!
Have fun!

Yes it is free, and as a matter fact Sun (Which created Java) is most of the way finished with even releasing the source code to it (Open Source).
I have used eclipse and NetBeans which are IDE (development environment) that will help you develop Java code. I prefer NetBeans because it is easier to setup. I should add both of these IDEs are also free.
You will need the JDK (Java Development Kit) to do development with. On this page you can find a download that will let you download both at the same time, making setup basically just install and run.
http://www.netbeans.info/downloads/index.php
Or for just the JDK (1.6 is the most current).
http://java.sun.com/javase/downloads/index.jsp
You will need the JDK even if you go with eclipse for an IDE.
The JDK SE (Standard Edition) is the main version for desktop applications and Web. There are other versions for working on the server side, and for developing for embedded applications, like what go into phones.
Be aware of the fact though that Java is different then PHP and has a longer learning curve. It is a strongly typed language unlike PHP where you don't have to define variables before you use them. Java is similar to C++, which classes, and such

Yes it is a free software...the runtime that is. To program in Java requires a developers package that costs money.

yes java is free software.
the java 2 software development kit(j2sdk) is freely down-loadable from :
java.sun.com
thats almost all of what u will ever require to program with java. it includes java compiler(javac),standard libraries, and java runtime environment(jre)
if u are one of those who require a IDE(integrated environment) get the NetBeansIDE from:
www.netbeans.org/downloads
an excellent IDE for Java .and whats more its FREE(even has a download-able c/c++ plugin).

Yes Java Runtime is free.
But to code Java programmes you need softwares like ECLIPSE, WASAD etc.
Or...
you can use notepad also, if you are very very good in typing (not doing typing mistakes), but its very difficult to debug the programmes when you use notepad.
