Hello p2p's

i want to know what is the use of declaring the constructors as private or protected.

Private or protected constructors are generally used to restrict instantiation of a class to a single object. This is often done through the Singleton design pattern.

Private constructors can also be useful for:
  classes containing only static utility methods
  classes containing only constants
  type safe enumerations
