Eclipse is installed on the computing lab PCs, under the Programs menu,
- In Eclipse, select File / New / Project
- Select "Next" (Java Project)
- Under "Project name:", type "Addition"
- Under "Contents", select "Create project from existing source", and
browse to the "Addition" subdirectory where you unpacked the ZIP file.
- Select the "Finish" button.
Browse the project
- If Eclipse's Java Browser is not visible, make it visible by selecting
Window / Open Perspective / Java Browsing.
- You should now have a list of projects shown in the top left, and Addition
should be one of the packages (probably the only one).
- Click on the project name "Addition"; it should show the packages in that
project (just the default package).

Installing Java on your own computer
You may also install Sun's Java SE Development Kit on your own computer. You
do so at your own risk; no official support will be given for development
environments other than Eclipse on the lab PCs.
Go to Sun's Java developer site (not the cheezy consumer java.com site)
- What you want is the JDK (Java Development Kit).
- You don't need the EE kit for fancy "Web2.0" applications. You don't want just the JRE (Java Runtime
Environment) because it doesn't include the javac compiler.
- The NetBeans IDE
is a cool free editor / development environment (equivalent to Eclipse); you
can try it but it's not needed to write and compile Java programs. It is a
- If you don't have an IDE (Eclipse, NetBeans, etc.), you can always use a
plain-text editor like Notepad, vim, etc. The compiler is named
javac, and the runtime environment to execute a Java class is named
- The CD included with the Deitel textbook also has the JDK, the NetBeans
IDE, a plain-text editor (jEdit), and other application.
