An adapter or wrapper is a component that provides a new interface for an existing component

An Adapter or Wrapper pattern is a broker pattern that provides a new interface for existing software so that it can be reused

Adaptation for reuse is an old technique that has been used since the beginning of software development

All of the mentioned

Discuss

Answer: (d).All of the mentioned

Q94.

The Adapter patterns provide object-oriented adapters in which of theses varieties?

One uses inheritance

one uses delegation

All of the mentioned

None of the mentioned

Discuss

Answer: (c).All of the mentioned

Q95.

A class (the adapter class) may be given a new interface by an adapter class in which of the two ways?

The adapter may subclass the adapter. The adapter can inherit adapter operations with appropriate semantics and pragmatics, override those with inappropriate semantics or pragmatics, and add operations needed for the new interface. This is the Class Adapter pattern

The adapter may hold a reference to the adapter and delegate must work to the adapter object. This approach is the Object Adapter pattern
