Prepare a report of at least 500 words summarizing your experience of writing the “Hello world!” program. Do you understand how the NotePad text editor and NetBeans work together? Did your program compile cleanly, or did it include errors? Were you able to identify and fix the errors? How many times did you need to fix and rebuild your program before it ran? Remember to spell- and grammar-check your paper and to include a title page.

Answer:
What is programming about?
There are two stories you can tell yourself about what this course is going to do for
you. The first is the traditional one that it is so you can learn some Java. Acquire
knowledge and skills. The second, which may be more interesting, is to see this
course as part of your journey as you start to become (or at least appreciate what
it is to be) a Computer Scientist. This second perspective suggests that there may
be something for you here whether or not you believe you are already skilled in
Java, and it challenges you to look beyond the mere details to the tought patterns
that link them together.
In the early days of computers programming involved a full understanding of
the way that the hardware of your computer worked, your program, when run,
took over essentially the whole machine and it had to include everything needed
to manage input and output. In extreme cases one started the process of loading code into a computer by using hand-switches to place bit-patterns directly
into the machine’s memory. After a while operating systems came along and
provided serious insulation from that level of extreme awareness of hardware, and
high-level languages make it possible to express programs in at least semi-humanunderstandable form. But still the emphasis was on “writing a program”, which
tended to be a stand-alone application that solved some problem.
Libraries of pre-written sub-programs grew up, but for a very long time the
ones that anybody could rely on having access to were either rather specialist or
the functionality that they provided was at a rather low and boring level. There
were libraries that could really help you with serious tasks (such as building a
windowed user-interface) but none of them gained really global acceptance, and
only a few were of any use on more than one brand of computer
