Benefits:
1. enable large scale reuse of S/W
2. Helps in improve developer communication
3. capture expert knowledge and design trade-offs and make
expertise widely available
Drawbacks:
1.Do not lead to direct code reuse
2. Complex in nature
3. they are deceptivrly simple
4. they are validated by experince and discussion

Answer / prits
Advantages:
A design pattern is:
•
a standard solution to a common programming problem
•
a technique for making code more flexible by making it meet
certain criteria
•
a design or implementation structure that achieves a
particular purpose
•
a high-level programming idiom
•
shorthand for describing certain aspects of program
organization
•
connections among program components
•
the shape of an object diagram or object model
DisAdvantages:
Design patterns may increase or decrease the
understandability of a design or implementation. They can
decrease understandability by adding indirection or
increasing the amount of code.

Answer / shashikant
Design patterns help overcome this problem because they teach the lessons distilled from experience by experts: patterns document expertise. Further, patterns not only describe how software is structured, but more importantly, they also describe how classes and objects interact, especially at run time. Taking these interactions and their consequences explicitly into account leads to more flexible and reusable software.

Answer / paul
The advantages are that design patterns are solutions to repetitive problems in object orientated programming (solutions that can be re-used over and over and applied to different areas and different problems). They are templates for you to base your solutions on.
Disadvantages are picking the correct design pattern and understanding how to implement that pattern to your scenario and knowing what to name your classes, so as to make it clearer for future programmers.

An additional disadvantage is :
1> They consume more memory because of generalised format
they are written, to store any kind of data .
