I just started trying to learn java coming from C++. Being a C++ guy, I 
must understand the details.


What is going on, as I debug through the static main method, my window 
is created and it is displayed, and responds. Yet, the debugger steps 
out of main...Which I would think exits the program.

Indeed I see threads in the debugger that look like it is in some built 
in method for exiting the program.

Did I make a new thread when I created a frame? If so, at what point? 
Why doesn't the program exit after main is done? What keeps it alive? 
Remember I am coming from the C Windows API and am used to a windows 
message pump...i.e. a loop where the program is executing, by 
dispatching messages.

Did I make a basic frame correctly? There seems to be 900 different ways 
of doing it.




I made this, doing my best to follow tutorials on the net:
