Here,
pkg
is the name of the package, which can include its full path, and
classname
is the
name of the class being imported. If you want to import the entire contents of a package,

*
) for the class name. Here are examples of both forms:
In the first case, the
MyClass
class is imported from
mypack
. In the second, all of the
classes in
mypack
are imported. In a Java source file,
import
statements occur immedi-
ately following the
package
statement (if it exists) and before any class definitions.
You can use
import
to bring the
bookpack
package into view so that the
Book
class can

import
statement to the top of any
file that uses
Book
.
For example, here is the
UseBook
class recoded to use
import
:
