Incidentally, I assume you meant "Can anyone tell me the programming
techniques used to implement garbage collection, in general?"

It's possible you meant something else by your questions.  For example:

   * What is garbage collection?
   * What behavior should I expect to observe from GC in Java?
   * I'm an expert in GC and need the techniques used by the JVM.

In these cases, you won't find help in any of the sources I mentioned.  
Neither of them even mentions Java, to the best of my knowledge, so they
can't speak to the spec's guaranteed behavior nor to any implementations
of the Java platform.  They also assume you already know what garbage
collection is.

If you meant one of the other questions and no other answers help,
please feel free to let us know.

It is not odd that people who understand the intricacies of Garbage
Collection algorithms are considered the acme of programmers.

ut in Java, we have a Garbage Collector. This is a little dude in
overalls that climbs down a special Staff Only Thread, sweeps up all
the broken Objects on the floor, and shovels them into the
incinerator. You  never know exactly when he's going to come along,
but he's always there  keeping an eye on the mess on the floor to make
sure that it doesn't  fill up too much...

The problem is the objects DON'T naturally fall to the floor. GC is
about tracing the root to the branches to see what is still alive.
Perhaps a copy collector would be easier to understand, copying only
the objects still properly attached to a new room,  shaking off the
dead wood, then turning on a blast furnace in the old one to vaporise
anything in it.
