Generalization defines a is-a-kind of relationship in which one class shares its structure and/or behavior with one or more other classes. The concept of generalization in UML is similar to inheritance in Java. It maps directly to the extends keyword. It is shown by a straight line originating from the subclass with a hollow arrowhead pointing at the nearest superclass.
