Create a JAR File Containing the Contract

> The first thing you need is a contract file. You can download and use this very basic sample file named contract. Or you can use any other file you like. Just be sure to name the file `contract` so it will work with the commands specified in this lesson.

> Once you've got the contract file, place it into a JAR file. In your command window type the following:

> >     jar cvf Contract.jar contract

> This command creates a JAR file named `Contract.jar` and places the `contract` file inside it.
