Attributes and Behavior
A Java class consists of two distinct types of information: attributes and behavior.
Both of these are present in VolcanoRobot, a project you will implement today as a class. This project, a computer simulation of a volcanic exploration vehicle, is patterned after the Dante II robot used by NASA's Telerobotics Research program to do research inside volcanic craters.
Attributes of a Class of Objects
Attributes are the data that differentiates one object from another. They can be used to determine the appearance, state, and other qualities of objects that belong to that class.
