Copying and Organizing Files
All of the examples for Java How To Program, Sixth Edition are included on the CD that accompanies this textbook. Follow the steps in the next section, Copying the Book Examples from the CD, to copy the examples directory from the CD onto your hard drive. We suggest that you work from your hard drive rather than your CD drive for two reasons: The CD is read-only, so you cannot save your applications to the book's CD, and files can be accessed faster from a hard drive than from a CD. The examples from the book are also available for download from:
www.deitel.com
www.prenhall.com/deitel
Screen shots in the following section might differ slightly from what you see on your computer, depending on whether you are using Windows 2000 or Windows XP, or your version of Internet Explorer.

Before you can run the applications in Java How To Program, Sixth Edition or build your own applications, you must install the Java Development Kit (JDK) 5.0 or another Java development tool. The following section describes how to install JDK 5.0.
[Page lxii]
Installing the J2SE Development Kit (JDK)
1.Locating the JDK installer. At the time of publication, the JDK 5.0 was still in beta releases and being updated frequently. As a result, the JDK installer might not be included on the CD that accompanies your book. If this is the case, you can download the most recent version of the installer from Sun's Web site. Go to java.sun.com/j2se/5.0/download.jsp and click the DOWNLOAD link in the SDK column. You must accept the license agreement before downloading. Once you accept the license agreement, you are directed to a download page, where you can select and download the installer for your computer platform. Save the installer on your hard disk and keep track of where you save it. The following steps show the installation procedure on the Windows platform.
2.Starting installation of the JDK. After either downloading the JDK installer or locating it on the CD that accompanies the book, double click the installer program to begin installing the JDK. The InstallShield Wizard window (Fig. 7) is displayed. Wait for the wizard to finish the configuration.
Figure 7. InstallShield Wizard for the JDK.
3.Accepting the license agreement. Carefully read the license agreement. Select Yes to agree to the terms (Fig. 8). [Note: If you choose not to accept the license agreement, the software will not install and you will not be able to execute or create Java applications.]

4.Choosing the installation directory for the JDK. Select the directory in which you want the JDK to be installed (Fig. 9). If you change the default installation directory, be sure to write down the exact name and location of the directory you choose, as you will need this information later in the installation process. After selecting a directory, click the Next > button to install the development tool.

5.Choosing the installation directory for the Java Runtime Environment (JRE). Select the directory in which you want the JRE to be installed (Fig. 10). We recommend that you choose the default installation directory. After you have selected a directory, click the Next > button to install the JRE.
