B) simplifies the aggregate interface
C) It promotes consistency among products
D) Sharing of objects
E) Families of related algorithms
F) A choice of implementation
G) Reduced Name space
H) Specifying new objects by varying value
I) Provides hooks for subclass

Is there a question somewhere in there?

[Don Kiddick]

and do your own homework ...

[Pradeep bhatt]

Gurumurthy,
I suggest you read GoF book.

E) Families of related algorithms,C) It promotes consistency among products
- Abstract factory pattern

[Ishita Gupta]

Hi,
B) Iterator pattern
D) Composite pattern
E) Factory method pattern
F) Chain of resopnsibility
Thanx
- SCJP2

[Pradeep bhatt]

How is E fatory method pattern. It should be abstarct factory method pattern

[Ishita Gupta]

Hi again,
Yes u r right Pradeep, E should be Abstract factory pattern.
But what about the others i mentioned, are'nt they all correct.
In the meanwhile i ll try to figure out what others are.
Thanx

A is interpreter pattern.
Book promotions are nice ways to get home work questions done. How I wish Javaranch was there when I was in college.

Grammar sounds a little bit like Interpreter, but I actually don't grok the description...

B) simplifies the aggregate interface
C) It promotes consistency among products

I don't understand these.

D) Sharing of objects

Could be Flyweight?

E) Families of related algorithms
F) A choice of implementation

Could both be Strategy.
Why do you think E is Abstract Factory???

G) Reduced Name space
H) Specifying new objects by varying value

Again, I don't even get the question.

I) Provides hooks for subclass

Template Method?

[Pradeep bhatt]

The Strategy pattern is very useful for situations where you would like to dynamically swap the algorithms used in an application.
Strategy is intended to provide you with a means to define a family of algorithms, encapsulate each one as an object, and make them interchangeable. Strategy lets the algorithms vary independently from clients that use them.

C) It promotes consistency among products

Cant this be abstract factory?
I understand consistency as using related products together as a family.
I am totally confused.

A) Implementing the grammar is easy too. - Interpreter
B) simplifies the aggregate interface - Iterator
C) It promotes consistency among products - Abstract Factory
D) Sharing of objects - Flyweight
E) Families of related algorithms -Strategy
F) A choice of implementation - Strategy
G) Reduced Name space - Singleton
H) Specifying new objects by varying value - Prototype
I) Provides hooks for subclass - Factory method
