Here is an interesting concept which I came across just recently and considered it worth sharing. I was reading about inner classes concepts where in, there is a type of inner class called the local inner class. Local inner classes are those classes which reside within the function of a method belonging to an outer class. The code can be something shown like this.
public class LocalInnerClassTest {
public void defineInnerClass() {
class MyLocalInnerClass {
public void doSomething() {
}
}
}
}Now lets suppose we want to pass a variable in the defineInnerClass() and pass it to the doSomething() for some computation, then according to the specifications on local inner classes methods we must declare the variables as final or else it will result in a compile time error. So the resulting code must be something as follows: Read the rest of this entry »
JavaWorld has published a useful research paper which discusses how to discern which design patterns and frameworks would work best for your enterprise applications, written by Chris Richardson. As a developer it is very essential to know about the different strategies one would adopt in a particular business scenario. This paper helps you in making important decisions about which design patterns would best suite a given set of requirements.
According to the research done by Chris for enterprise applications, here are some of the important points which the paper elaborates:
- Make use of the POJO approach, with lightweight frameworks like Hibernate for ORM and Spring AOP for transactional activities.
- EJB 3 makes it possible to have your business logic sit within your POJO and also make it run outside the container which makes it really usable.
- Implementing 3 tiers for an application which commonly include
- Presentation tier
- Business Interfaces for encapsulation + Business tier logic in classes
- Persistence tier for handling transactions and concurrency
- The design should involve,
- Modeling your business classes appropriately
- Code structuring principles for easier maintenance
While the above points are usually very well known amongst the developer community, it helps if you know which decisions should be taken when. Design patterns which have been established over the years play a key role in making such decisions. The white paper explains a few of the design patterns which are particularly mentioned when enterprise applications are into consideration.
I would like to enumerate here, some of the different design patterns which are Read the rest of this entry »

I had been using fluid designs over a couple of months until the big screens came into picture. The fluid designs became so drastically different on those big screens that I found all my imagined design going down the drain. The web site rendered itself in such an ugly manner that it came down to negative remarks of the big flat screen owner. So the ultimate question to me was, why did I choose a fluid layout in the first place?
