CS 201 - Installing Java and Eclipse

1. Install the Java JDK (Java Development Kit), version 1.7 ("Java 7")
   • Windows and Linux users: Instructions can be found at http://www.java.com/en/download/help/download_options.xml. The actual files can be found at: http://java.com/en/download/index.jsp. Remember whether you installed the 32-bit or 64-bit version.
   • Mac users: If you've been running software update regularly (under the Apple menu), you probably have the latest version. To check, open terminal and type "java -version". The version number should start with 1.7. If it doesn't, go to the links above and download the latest version. This command will also indicate whether your version is 32-bit or 64-bit.

2. Download and install Eclipse from http://www.eclipse.org/downloads/. Download "Eclipse IDE for Java Developers", and select 32-bit or 64-bit to match your version of Java.

3. For a few of the assignments, we'll be using some of the code from the Bailey book. Download bailey.jar from http://dept.cs.williams.edu/~bailey/JavaStructures/Software.html and save it in a permanent location, e.g., your cs201 folder or within the Eclipse installation folder (for Windows, this might be C:\eclipse). Next, tell Eclipse where to find this file:
   • Start Eclipse.
   • Open the Window menu and select Preferences. (On Macs, Preferences is found in the main Eclipse menu.)
   • Click on the icon to the left of Java to expand the Java choices.
   • Expand Build Path and then select Classpath Variables.
   • Click the New button.
   • For the name, enter BAILEY. Be sure to spell it exactly like this and in all capitals.
   • For the Path, click the File button and find the bailey.jar file you just downloaded.
   • Click OK and OK again.

4. Now, if you want to use Bailey's structure package in a project:
   • Open the project and select "Project Properties"
   • Select "Java Build Path",
   • Select the "Libraries" tab
   • Click on "add variable" and select BAILEY.

That's it!

Creating new projects

1. Open the "File" Menu. Select "New" and then "Project" from the submenu.
2. Select "Java Project", which may be showing at the top level or you may have to open the Folder labeled "Java" to find it, and then click "Next".
3. Enter the Project name.
4. Make sure the "Create separate folders for sources and class files" is selected.
5. If you are not planning to use Bailey's library, click Finish and skip the rest of the steps. If you are planning to use Bailey's code, click Next.
6. Select the "Libraries" tab.
7. Click "Add variable".
8. Select BAILEY from the list and click "OK".
9. Click "Finish".
