Summary of Creating and Using Packages

> To create a package for a type, put a `package` statement as the first statement in the source file that contains the type (class, interface, enumeration, or annotation type).

> To use a public type that's in a different package, you have three choices: (1) use the fully qualified name of the type, (2) import the type, or (3) import the entire package of which the type is a member.

> The path names for a package's source and class files mirror the name of the package.

> You might have to set your `CLASSPATH` so that the compiler and the JVM can find the `.class` files for your types.
