Class diagram

3

What is an association in UML?

a

A constraint

b

A type of class

c

A method

d

A link between two or more classes

4

Which relationship represents 'has-a' or composition?

a

Inheritance

b

Association

c

Composition

d

Dependency

5

Which diagram is best for showing object interactions over time?

a

Deployment diagram

b

Sequence diagram

c

Activity diagram

c

A contract of methods a class can implement

d

A concrete class implementation

7

Which diagram models workflows and activities?

a

State machine diagram

b

Class diagram

c

Activity diagram

d

Package diagram

8

What is a stereotype in UML?

a

A way to extend UML semantics

b

A data type

c

A type of diagram

d

A programming language

9

Which relationship indicates generalization?

a

Dependency

b

Association

c

Inheritance

d

Realization

10

What is a use case diagram used for?
