As I have worked heavily in C/C++ development, I am quite familiar

came to know that the synchronization techniques are some what
different, due to the memory model and performance optimization. And
then, I tried what I thought would work. But failed to achieve it
exactly.

Every object has a monitor (i.e., built-in mutex). When you use
'synchronize(reference)', you lock a critical section with the monitor built
in to the referent. There are other techniques - 'volatile' variables provide
some simple, fast synchronization. The java.util.concurrent and related
packages provide all sorts of concurrency structures.

The Java tutorials on java.sun.com scratch the surface of concurrency
education for Java. Articles on the IBM DeveloperWorks/Java site go into
depth. One of the more authoritative writers there, a co-developer of Java's
concurrency libraries, Brian Goetz, is the principal author of /Java
Concurrency in Practice/, a seminal text on the matter. Doug Lea's writing is
also significant.
