The JRE includes a virtual machine for running Java programs, the JDK
is stuff like the Java compiler and associated programs you need to
build and debug Java code.

You can choose to use Java's non-free javac compiler (apt-cache search
sun java jdk), gcj, or OpenJDK.

> 3. Are there any free software implementations of Java?

Yeah, gcj and OpenJDK are the big ones. OpenJDK is a fully comformant
implementation of Java and I have not run into any problems with it at
all; it's Sun's official open implementation of Java.

Unfortunately, OpenJDK is too new to be packaged for etch, but you can
try to build it from sources.
