In singleton class, what about the variable. Is there we use private constructor?

Nice example @Rajeesh.

I cannot understand the concept of singleton class I think it can be virtual class.

Object created to the only one class called singleton class.

Singleton class is useful in real time application. Take the example of a real time application of Hospital administration system. Whenever you register in the Hospital database, your object is created and you will be provided with a unique number. This ID is only refers to you created only once in lifetime. Just imagine that you are going to a Hospital first time and to see a Physician. Then you are registering your name in the database only once. Next time, if you plan to visit a Cardiologist in the same hospital. Do you think that your ID needs to be created again? Not all right. Because you have already registered before there is no need to create another object again.

Here comes the singleton class concept. We can create only instance that serves the purpose in every time.

Hope you understand the concept well.
