SIZE="-2"><SUP>TM</SUP></FONT> language,have some experience with other languages, and are familiar with things like displaying text or graphics or performing simple calculations, this tutorial could be for you. It walks through how to use the Java® 2 Platform software to create and runthree common types of programs written for the Java platform—applications, applets,and servlets. <P>You will learn how applications, applets, and servlets are similar and different, how to build a basic user interface that handles simple end user input, how to read data from and write data to files and databases, and how to send and receive data over the network. This tutorial is not comprehensive, but instead takes you on a straight and uncomplicated path through the more common programming features available in the Java platform. <P>If you have no programming experience at all, you might still findthis tutorial useful; but you also might want to take an introductory programming course or read <A HREF="http://www1.fatbrain.com/asp/bookinfo/bookinfo.asp?theisbn=0672316684">TeachYourself Java 2 Online in Web Time</A> before you proceed.<HR><A NAME="contents"></A><H3>Contents</H3>Lesson 1: <A HREF="compile.html">Compiling and Running a Simple Program</A> <UL> <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif"><A HREF="compile.html#platform">A Word About the Java Platform</A></FONT> <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif"><A HREF="compile.html#setup">Setting Up Your Computer</A></FONT> <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif"><A HREF="compile.html#simple">Writing a Program</A></FONT> <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif"><A HREF="compile.html#comp">Compiling the Program</A></FONT> <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif"><A HREF="compile.html#run">Interpreting and Running the Program</A></FONT> <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif"><A HREF="compile.html#debug">Common Compiler and Interpreter Problems</A></FONT> <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif"><A HREF="compile.html#comm">Code Comments</A></FONT> <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif"><A HREF="compile.html#api">API Documentation</A></FONT> <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif"><A HREF="compile.html#more">More Information</A></FONT> </UL><P>⌨️ 快捷键说明
