In a computer terminology, package is a collection of the related files in the same directory. Package avoids naming conflicts between the files and make possible to use them in an easier way.
In the same manner, Java package is a group of related types classes and interfaces, which provides access protection and name space management to use those classes and interfaces in a particular Java program. These packages can be stored in compressed files called JAR files that allow you to download the classes faster as a group rather than one at a time.
