文档介绍：How Java Works
by Marshall Brain
Have you ever wondered puter programs work? Have you ever wanted to learn how to
write your puter programs? Whether you are 14 years old and hoping to learn how to
write your first game, or you are 70 years old and have been curious puter
programming for 20 years, this article is for you. In this edition of HowStuffWorks, I'm going to
teach you puter programs work by teaching you how to program in the Java
programming language.
In order to teach you puter programming, I am going to make several assumptions
from the start:
• I am going to assume that you know nothing puter programming now. If you
already know something then the first part of this article will seem elementary to you.
Please feel free to skip forward until you get to something you don't know.
• I am going to assume you do know something about puter you are using. That is,
I am going to assume you already know how to edit a file, copy and delete files, rename
files, find information on your system, etc.
• For simplicity, I am going to assume that you are using a machine running Windows 95,
98, 2000, NT or XP. It should be relatively straightforward for people running other
operating systems to map the concepts over to those.
• I am going to assume that you have a desire to learn.
All of the tools you need to start programming in Java are widely available on the Web for free.
There is also a huge amount of educational material for Java available on the Web, so once you
finish this article you can easily go learn more to advance your skills. You can learn Java
programming here without spending any money pilers, development environments,
reading materials, etc. Once you learn Java it is easy to learn other languages, so this is a good
place to start.
Having said these things, we are ready to go. Let's get started!
A Little Terminology
Keep in mind that I am assuming that you know nothing about programming. Her
