Singleton Design Pattern is used when we would like to have a single instance. A class distributes the only instance of itself. It will be used with Connection Pool usually.

Singleton design pattern is used to create only one instance.
I want to a an example when we are using this singleton design pattern in real life.

generally the dao classes like insertDao,updateDao,deleteDao for all these cases we make it as a singleton object and put in factory methods .If we require any dao then we
go to factory and get the dao object. because of singleton the facory is going to return same object for multiple times. in real time applications we no need to create same object multiple times.
