Package

A package is a collection of related classes and interfaces providing access protection and namespace management.

The format of the package declaration is quite simple. The keyword package occurs first, and is followed by the package name. The package name is a series of elements separated by periods. When class files are created they are placed in a directory hierarchy that reflects their package names. You must therefore be careful that each component of your package name hierarchy is a legitimate directory name on all platforms. Therefore, you must not use characters such as the space, forward slash, backslash, or other symbols.

Example:

package allapplabs.com;

class glossary{
...
}

Here, allapplabs and com are directories where com is the sub-directory of allapplabs and class glossary is in allapplabs.com package.
