- Download to run and explore the java file (see below) from the video on your own in eclipse. You may download the standalone *.java file for this example. To run the standalone *.java file you will need to
create a new Eclipse project, then
create a package within the project called “example” (the package named at the top of the class MUST match the package the file is placed in within the Eclipse project), and finally
download and import the standalone *.java file(s) to the created package.
