A package is a group of related classes.
Some standard packages are java.awt
and java.util
To create a package, put a package
declaration at the beginning of each file containing the class definitions that are to belong to the
package.
package
geometry;
public class Dodecahedron {
// ...
}
public class Icosahedron {
// ...
}
Nested packages are permitted. When
imported, their class files must be located in subdirectories of their outer package directories.
