The boundary between detailed design and architectural design is fuzzy.

Back 1

Front 2

UML allows specification of multiple inheritance.

Back 2

An abstract class may contain only concrete operations in UML.

Back 3

True

Front 4

In UML, a generalization connector may have multiplicities.

Back 4

False

Front 5

In UML, if an association line has no markings on its ends, then it is not
navigable in either direction.

Back 5

False

Front 6

It’s ok to use inheritance to obtain pull implementation of operations in some
other class into a new class because it saves time writing code.

Back 6

False

Front 7

In UML sequence diagrams, a lifeline is a solid vertical line.

Back 7

False

Front 8

In UML (and in computer science generally) an operation is still active when it is suspended.

Back 8

True

Front 9

According to the Law of Demeter, a sequence of operation calls like o.f().g() is a good idea.

Back 9

False

Front 10

The Law of Demeter encourages a delegated control style.

Back 10

True

Front 11

Every UML state diagram must have a single initial pseudo state and a single
final state.

Back 11

False

Front 12

In UML state diagrams, final states may contain entry actions.

Back 12

False

Front 13

In UML state diagrams, an internal transitions do not exit or enter a state.

Back 13

True

Front 14

In UML state diagrams, a transition to the boundary of an outer state requires
that exactly one nested state be designated as an initial state.

Back 14

True

Front 15

Iterators should only be used when there is no alternative way to traverse a
collection (such as indices in a list).

Back 15

False

Front 16

The Façade pattern is used to change a class’s interface.

Back 16

False

Front 17

The Façade pattern can be used to help decouple a sub-system from the clients who use it.

Back 17

True

Front 18

In the Proxy pattern, the broker and the supplier share an interface, but not in the Adapter pattern, they never do.

Back 18

True

Front 19

The Mediator pattern can be thought of has a variation of the Façade pattern in which several different classes use the same Façade.

Back 19

True

Front 20

In some circumstances, the Object Adapter pattern cannot be used, but the Class Adapter pattern can be used.

Back 20

False
