In a UML diagram a line with an open arrowhead from a subclass to a superclass indicates

_polymorphism_________ allows subclasses to have methods with the samenames as methods in their superclasses.ANS:2.The __isinstance________ function determines whether or not an object is aninstance of a specific class or an instance of a subclass of that class.ANS:3.A subclass is also called a(n) ____derived______ class.

ANS:4.A superclass is also called a(n) ____base______ class.ANS:5.When a subclass method has the same name as a superclass method, thesubclass method _overrides________ the superclass method.ANS:6.In an inheritance relationship, the extended class is called the

Here's some explanations from the Visual Studio 2015 docs:

5: Association: A relationship between the members of two classifiers.

5a: Aggregation: An association representing a shared ownership relationship. The Aggregation property of the owner role is set to Shared.

5b: Composition: An association representing a whole-part relationship. The Aggregation property of the owner role is set to Composite.

9: Generalization: The specific classifier inherits part of its definition from the general classifier. The general classifier is at the arrow end of the connector. Attributes, associations, and operations are inherited by the specific classifier. Use the Inheritance tool to create a generalization between two classifiers.

13: Import: A relationship between packages, indicating that one package includes all the definitions of another.

14: Dependency: The definition or implementation of the dependent classifier might change if the classifier at the arrowhead end is changed.

15: Realization: The class implements the operations and attributes defined by the interface. Use the Inheritance tool to create a realization between a class and an interface.

16: Realization: An alternative presentation of the same relationship. The label on the lollipop symbol identifies the interface.

Properties of an Association

Aggregation: This appears as a diamond shape at one end of the connector. You can use it to indicate that instances at the aggregating role own or contain instances of the other.

Is Navigable: If true for only one role, an arrow appears in the navigable direction. You can use this to indicate navigability of links and database relations in the software.

Generalization: Generalization means that the specializing or derived type inherits attributes, operations, and associations of the general or base type. The general type appears at the arrowhead end of the relationship.

Realization: Realization means that a class implements the attributes and operations specified by the interface. The interface is at the arrow end of the connector.
