I wish to point out that there are two Java's out there, and
both include the Java Virtual Machine.

The full Java -JDK or Java Development Kit- is a full blown
Java suite, with compilers etc.  You only need this if you
are developing applications to run under Java.  It includes
the JVM.

The run-time only, JRE, has only the stuff needed to RUN
Java applications.  I believe the latest version is 1.1.17-v3b.

I have downloaded some programs here that run under Java, and
all the suggestions were that I needed the JDK....but I gave
the JRE a shot, and bingo, they work just fine at a tremendous
savings in disk space and installation headaches.

For instance, before you can install and use the JDK, you need
to install about 20 other packages.  The JRE, on the other hand,
is standalone.  This could save you hours of work, besides which
you do not need to know a thing about Java to get going.  This
was my case: I just wanted to run "MoneyDance", a Quicken-like
product for Linux that runs under the Java Virtual Machine.
All the links and info pointed at JDK, but I used JRE and it
worked.  

MoneyDance does not state it needs JDK, only the JVM.  Its just
that the links all point to JDK.  Good thing I tried JRE.
