What is an association?

• A relationship between two classes
• A relationship between two objects
• A link between two classes
• A link between two objects

What is an attribute?

• A relationship between two classes
• A parameter of an operation or method
• A data value held by an object in a class
• The return value from an operation

What is meant by the multiplicity of an association?

• The number of associations in a class
• The number of associations between two classes
• How many instances of one classrelate to how many instances of another class
• How many instances of one classrelate to a single instance of another class.

Inheritance 

• the method or methods and/or attributes defined in an object class can be reused by another object class
• is the inclusion within an object of all the resources needed for the object to function
• allows programmers & designers to separate catergories and concepts from instances of implementation so that they do not depend on software or hardware
• means "many forms" applied to object-oriented techniques it means that the same name behaviour may be completed differently for diffrent objects/classes

Polymorphism

• the method or methods and/or attributes defined in an object class can be reused by another object class
• is the inclusion within an object of all the resources needed for the object to function
• allows programmers & designers to separate catergories and concepts from instances of implementation so that they do not depend on software or hardware
• means "many forms" applied to object-oriented techniques it means that the same name behaviour may be completed differently for diffrent objects/classes

Encapsulation 

• the method or methods and/or attributes defined in an object class can be reused by another object class
• is the inclusion within an object of all the resources needed for the object to function
• allows programmers & designers to separate catergories and concepts from instances of implementation so that they do not depend on software or hardware
• means "many forms" applied to object-oriented techniques it means that the same name behaviour may be completed differently for diffrent objects/classes

Abstraction

• the method or methods and/or attributes defined in an object class can be reused by another object class
• is the inclusion within an object of all the resources needed for the object to function
• allows programmers & designers to separate catergories and concepts from instances of implementation so that they do not depend on software or hardware
• means "many forms" applied to object-oriented techniques it means that the same name behaviour may be completed differently for diffrent objects/classes

Is a class a description of an object?

• Yes
• No
