Question

what is java dynamic proxy,lot of tutorials are there but they are confusing me ,where we are using this concept , any one explain with real world application usage

Answer 1

Perhaps the documentation can offer some input:

Dynamic proxy classes are useful to an application or library that needs to provide type-safe reflective dispatch of invocations on objects that present interface APIs. For example, an application can use a dynamic proxy class to create an object that implements multiple arbitrary event listener interfaces– interfaces that extend java.util.EventListener— to process a variety of events of different types in a uniform fashion, such as by logging all such events to a file.

It also provides several examples.
