Understanding java packages


	Lesson 2 Objective	Understanding packages Examine packages and the role they play in Java class organization.
		To aid in the organization of classes, Java provides a construct known as a package that is used to organize classes into functionally-related groups. Packages do not directly impact the internal makeup of a class but they do impact the relationship between classes. All of the classes in the Java API are organized into a group of packages. The standard `java.lang` package is the only package that is automatically imported into every Java program. Packages help you uniquely identify classes. The package to which a class belongs is implicitly part of the class name. So the standard Java class `Graphic` is really named `java.awt.Graphics`. This identification helps to provide structure to all Java classes.
