This pattern helps us to separate the construction of a complex object from its representation so that the same construction process can create different representations.

11.

In this pattern, normally each receiver contains reference to another receiver. If one object cannot handle the request then it passes the same to the next receiver and so on.

12.

13.

1 point

This pattern is used to delegate the object creation to another...

14.

1 point

We use this pattern when we need to create thousands or more objects that share some common information.

15.

1 point

A graphic presentation of the static view that shows a collection of declarative model elements and their contents and relationships

16.

1 point

Vending Machine is one example of it.

17.

1 point

Diagram used to document the various model that a class can go through.

18.

1 point

This allows traversing of lists, trees and other structures in a standard manner.

19.

1 point

In this pattern, a class behavior or its algorithm can be changed at run time.

20.

1 point

This design pattern provides a simple interface to large code.

21.

1 point

This pattern provides a class which normally handles all the communications between different classes and supports easy maintainability of the code by loose coupling.

22.

1 point

Diagram that represents an external view of the system

23.

1 point

This pattern allows adding of new functionality in an existing object without altering its structure.

24.

1 point

Diagram similar to a class diagram but focuses on the instances of classes.

25.

1 point

With this pattern, The client never knows that it is working on an object which has many other objects inside it.

26.

1 point

This pattern describes how the communication between the entities is controlled in a good manner and also defines the instructions grammar.

27.

1 point

It describes how tightly a class or routine is related to other classes or routines.

28.

1 point

With the help of this pattern, the new operations are performed on an existing structure.

Relationship that requires each object to have a reference to the other object(s).

31.

1 point

In this pattern, two incompatible types can communicate between each other.

32.

1 point

With this pattern a request is wrapped under an object as command and passed to invoker object.

33.

1 point

If creating an object is expensive in time or computer resources, it allows you to postpone this creation until you need the actual object.

34.

1 point

Useful when a single, global point of access to a limited resource is required.

35.

1 point

These design patterns describe how objects and classes can be combined and form a large structure.

36.

1 point

This is used to instantiate a class by copying, or cloning, the properties of an existing object.
