JavaScript

The compiler reads a. The compiler requires a command line. If you saved the file into a newly created J21work folder inside the root folder on your main hard drive, the following MS-DOS command will open that folder:. When you are in the correct folder, you can compile Ellsworth.

The SDK compiler does not display any message if the program compiles successfully. If there are problems, the compiler lets you know by displaying each error along with a line that triggered the error. If the program compiled without any errors, a file called Ellsworth. The class file contains the Java bytecode that will be executed by the Java interpreter. If you get any errors, go back to your original source file and make sure that you typed it exactly as it appears in Listing 1. After you have a class file, you can run that file using a Java interpreter.

The SDK's interpreter is called java , and it also is run from the command line. Run the Ellsworth program by switching to the folder containing Ellsworth. You should see the Henry Ellsworth quotation displayed along with his name, job, and the place he wrote it. NOTE: Make sure to leave off the. If you leave off the. Help for Windows users with this problem is provided in Appendix A. You will begin learning about the syntax and structure of a Java program tomorrow -- the purpose of today's tutorial is to compile and run a program successfully.

For now, it can be instructive to simply read source code such as Ellsworth. If the Ellsworth program were written in English instead of Java, the 16 lines could take the following form:. Don't worry if you didn't guess right on the function of these lines -- everything used in the Ellsworth program will be completely introduced this week. This has a good side -- a proven market for Java programmers exists at present and the skills are in huge demand.

Five years ago you couldn't find "Java" in a classified ad outside of Silicon Valley, and even there the market consisted of Sun, Netscape, and only a few others. This also has a bad side -- Java is at least five times as large today as it was upon its first release, so there's much more to learn. For this reason, today was the last day for Java to be described in the abstract. The next 20 days will be spent at the command line, creating Java applications and applets, running them with the interpreter or a Web browser, and exploring the fundamental concepts of the language.

Q: The license for the SDK is only for days. I thought the kit was free -- don't you think you should have mentioned that rather predominately in your book? A: Sun Microsystems has always made the SDK available for free, and it seems highly doubtful at this point that the company would change the policy. Although Sun has not made any official statements regarding the duration of the license, it appears to be a way to encourage developers to upgrade to new versions when they become available.

Sun updates the SDK frequently, by issuing either a bug- and security-fix minor upgrade or a full upgrade such as the move to Java 2. Q: Java 1. Java 1.

Why is Java 2 using SDK 1. A: Sun changed its naming scheme after Java 1. The language was renamed Java 2 to capitalize on all the different products and technologies available in addition to the Software Development Kit. As a result of the changes, Java 1. Sun, which received industry praise for the marketing savvy behind the choice of "Java" as a name for the language, has created a lot of confusion with this new numbering.

The current version of the language is called Java 2 and the current software development kit is Software Development Kit 1. The best way to figure out whether you're using the right version is to use SDK 1. Where applicable, exercise solutions are offered on the book's Web site. Cringely In , when Sun Microsystems first released the Java programming language, it was an inventive toy for the World Wide Web that had the potential to be much more.

First used to create simple programs on World Wide Web pages, Java can be found today in each of the following places and many more: Web servers Relational databases Mainframe computers Telephones Orbiting telescopes Personal digital assistants Credit card-sized "smartcards" Over the next 21 days, you will write Java programs that reflect how the language is being used in the 21st century.

You'll also become a Java programmer with a lot of potential. Exploring Java 2 Whenever Sun releases a new version of Java, it makes a free development kit available over the Web to support that version.

Today's goals are reasonably modest. You'll learn about the following topics: What Java is like today and how it got there Why Java is worth learning Why Java is being chosen for software projects What you need to start writing Java programs How to create your first program Java's Past, Present, and Future Based on the enormous amount of press Java has received over the past several years and the huge number of books about Java, you might have an inflated impression of what Java is capable of.

Java programs that don't run within a Web browser are called applications. Java Grew from a Little Oak The Java language was developed at Sun Microsystems in December as part of the Green project, a small research effort into consumer electronics. Many of the things that made Java good for the Star 7 turned out to be good for the Web: Java is small -- Programs load reasonably quickly on a Web page Java is secure -- Safeguards protect against programs that cause damage, whether accidental or intentional Java is portable -- Owners of Windows, Macintosh, Linux, and other operating systems can run the same program in their Web browsers without modification In order to demonstrate Java's potential, in project members created HotJava, a Web browser that could run Java applets.

Versions of the Language Sun has released four major versions of the Java language: Java 1. Java's Outlook Anyone who can accurately predict the future of Java should be going after venture capital instead of writing a book. The new version of Java 2 incorporates the following key improvements: HotSpot -- A new technology that runs Java programs more quickly and takes up less memory JavaSound -- Greatly enhanced support for 8- and bit playback and recording of WAV, AU, AIFF, and MIDI sound formats Swing -- More than two dozen added features to components used in the graphical user interface of Java programs Performance -- In addition to HotSpot, Sun has improved the speed and reliability of several aspects of the language: animation, database connectivity, networking, and multi-threaded programs, which handle multiple tasks at the same time You will work with these and other new features in the next three weeks.

Why to Choose Java Java applets were a breakthrough in interactive content on the Web, and many top sites used them to deliver news, present information, and attract visitors. Java Is Object-Oriented If you're not yet familiar with object-oriented programming, you get plenty of chances to become so during the next week. Java Is Platform Neutral Because it was created to run on a wide variety of devices and computing platforms, Java was designed to be platform neutral, working the same no matter where it runs. Diving into Java Programming Now that you've been introduced to Java as a spectator, it's time to put some of these concepts into play and create your first Java program.

A command-line program is one that must be run by typing a command at a prompt. Here's an example of a command you could type when using the development kit: javac RetrieveMail.
