<P>Several alternatives are available for the development of Java, including Sun products (Java Workshop, Java Developers Kit (JDK)), Metrowerks’ CodeWarrior, Symantec products (Visual Café, Visual Café Pro, Café), Natural Intelligence Roaster, Microsoft J++, Asymetrix SuperCede, and others. For more details, see <A HREF="http://www.javasoft.com/products/jdk/">http://www.javasoft.com/products/JDK/</A>, <A HREF="ftp://ftp.metrowerks.com/pub/">ftp://ftp.metrowerks.com/pub/</A>, <A HREF="http://www.metrowerks.com/">http://www.metrowerks.com/</A>, <A HREF="http://www.symantec.com">http://www.symantec.com</A>, <A HREF="http://www.roaster.com/roaster/">http://www.roaster.com/roaster/</A>, and <A HREF="http://www.microsoft.com/java/">http://www.microsoft.com/java/</A>.</P>
<P>J++ is available for Windows 95/NT. Workshop is available only for Solaris and Windows 95/NT. Roaster is available for MacOS. Symantec products and CodeWarrior are available for MacOS and Windows 95/NT. SuperCede is available for Windows 95/NT. JDK is available on all platforms (MacOS, Windows 95/NT, and Solaris). We will cover a few of these products in the following sections.</P>
<P>Feedback from students, and the authors’ experience, has led to the conclusion that a good compiler is a worthwhile investment. Free tools (such as JDK) are good to have around, too. Some of the more expensive products are easier to use and faster to run. You should plan to purchase more than one compiler.</P>
<P>Some programmers would like to use code that has been written in C. As far as we know, the only compiler that supports linking to C is Metrowerks’ CodeWarrior. Also, CodeWarrior comes with C, C++, Pascal and Java. CodeWarrior is an integrated development environment (IDE) that directly supports native method programming.</P>

<P><FONT SIZE="-1"><HR><B>CD-ROM: </B>The CD-ROM that comes with this book has several example tools, and you’re encouraged to try them. The primary example software is DiffCAD, a Java application that resides in several files. Upon opening the CD-ROM, the Mac user should look into the Mac folder to find a self-extracting archive such as the one shown in Figure 1.9.<HR></FONT>

<P>As of this writing, Metrowerks has Professional Release 1 of the CodeWarrior IDE for the Windows 95/NT environment. It comes with Pascal, C, C++ and Java. There are also academic versions available at a discount.

<P>Three strong points of CodeWarrior IDE are:
</P>
<DL>
<DD><B>•</B> CodeWarrior also compile Pascal, C, C++, and Java.
<DD><B>•</B> The CodeWarrior IDE for Windows 95/NT has the same look and feel as the MacOS version.
<DD><B>•</B> Metrowerks states that it intends to release a version of CodeWarrior for Solaris, a Sun UNIX operating system.
</DL>
<P>When the Metrowerks Unix release is ready, the CodeWarrior IDE will work on the Solaris, MacOS, and Windows 95/NT platforms.
