     I'd recommend against this course, at Naarayana's current stage of
learning.  IDE's are indeed useful tools, but they are complex tools
that take time and effort to learn.  A beginner, I think, would be
better off with a command line and a plain-vanilla file editor, so as
not to be confronted with learning Java *and* a complicated IDE at the
same time.  Too steep a learning curve, plus the chance to get confused
about what Java does and what the IDE does.

     A way to accomplish much of this without needing to learn how to use
somebody's debugger is to sprinkle the code with print statements that
display the values of "interesting" variables.  They are easy to insert,
easy to remove -- and easy to understand.
