For example, say you have a class vehicle which defines the basic functionality (methods) and components (object variables) that vehicles have in common. you cannot create an object of vehicle because a vehicle is itself an abstract, general concept. The last things to mention are that abstract classes can also implement methods, despite providing just their signature and that an abstract class may have static fields and static methods. in this example, we use the following tools on a windows 7 platform: eclipse kepler service release 1 java 1.7.0 51 1. using a java abstract class the purpose of an abstract class is to specify the default.
