Spring Framework

Java typically consists of number of objects that collaborate with each other for an application to behave properly. In other sense one object depends on other for functioning. Java provides us with so many functionalities for building applications right from objects, classes, rich full featured application servers and web frameworks, but it is up to developers and architects on how to put all these to build an application. There are number of design patterns that can be used to compose various classes and object instances that make up an application. But these patterns are just that, we do not know given the name of a design pattern what it does, where it is used, where it is best applied, the pros and cons of the patterns.
