Convert the interface of a class into another interface clients expect

The following will compile with no errors float abc = 2;

Attach additional responsibilities to an object dynamically, provide a flexible alternative to sub classing for extended functionality

Separate the construction on a complex object from its representation so that the same construction process can create different representations

Define an object that encapsulates how a set of objects interact. Promotes loose coupling by keeping objects from referring to each other explicitly and lets you vary their interaction independently

Use sharing of data to support large number of fine grained objects effectively

Avoid coupling of sender of a request to its receiver by giving more than one object a chance to handle the request .Link the receiving object and pass the request along the list until an object handles it

Provide a way to access the elements of an aggregate object sequentially without exposing its underlying representation.

Used to model, represent, and manage a set of interrelated persistent objects rather than representing them as individual fine-grained beans.

Which pattern hides the underlying implementation details of the business service, such as lookup and access details of the EJB architecture.
