Summary: Creating a JAR package in Eclipse
The instructions for submitting homework require you to package the class files as an executable JAR
file. An executable JAR is a good format also for bringing your solution to class. Here's how you do an
executable JAR in Eclipse:
1. First, create a project for the Hello World and import the source as described in Section 1.

2. From the "File" menu -> "Export ..."
3. "Select": JAR file

5. "JAR Package Specification": Select the files that you will include into the JAR. For our
"Hello, World!" example, this is just the Java source file "Hello.java". You don't need to

6. Tick the box to "Export generated class files and resources" and "Export

7. Select a suitable destination for the output (.JAR) file.
