I'm trying to make a program that works like the calculator in Windows
Accessories - all input is from button clicks. Below I listed a
stripped down version of the GUI and a little of the processing behind
it. It is in two small files. I had intended that the program would
display a sequence of digits from button clicks, which I would then
convert into a Double precision number. The problem is I am constrained
to initialize the string within the method that accumulates the sequence
of digits. Everytime the method is called the string is reinitialized
with the result that my sequence of digits is only ever one digit long.
My plan would work if I could initialize the string outside the method,
however variable scope in Java doesn't allow it.

I'm going back to the base article, to suggest a basically different
approach.
During my spare time over the last couple of weeks I've been studying an
unfamiliar C++ graphics library. I realized that my normal approach to
learning languages and libraries was entirely different from yours.
I wrote a series of very simple, small programs, each of which
introduced only one new technique. For example, my program for learning
to connect a button to the code that should run when it is clicked
created a window containing one button, and wrote "hello" to standard
out each time it was clicked. When that was working I advanced to two
buttons doing different things.
Each learning program incorporated at most one new technique. The
programs I was really trying to write did not use any new graphics
techniques - I had tried everything out in smaller programs.
Have you considered a step-by-step approach, as an alternative to
writing an application and then trying to make it work?
