will the book implementing patterns will help in creating new and complex data structures and improve the time of execution of java code

It will certainly help developing complex structures by giving you the patterns for encapsulating the data and the complexity as well as managing these now less complex units of your domain model.

Regarding performance. If you have communicative, _simple_ and flexible code it is much easier to improve performance of the bottlenecks of your system.

So it helps in both ways.

Jatandar,

The patterns don't address optimization. Ken Auer and I wrote a paper called Lazy Optimization in "Pattern languages of program design 2" talking about performance.

As far as complex data structures, the patterns won't help directly but they will help you communicate your intentions in the resulting code. My bias, is to avoid the need for complex data structures but when I need one, I want it to be as easy to understand as possible since such structures often need to be changed.
