A singleton class must create its own unique instance.3. A singleton class must provide thi
1. Description:
Guarantees that a class has only one instance and provides a global access point to access it.
2. The single case model has 3 main features:
2.1 Singleton classes Ensure that you have only one instance.2.2 The Singleton class must create its own instance.The 2.3 Singleton class must provide a unique instance for other objects.
3. Implementation: Lazy single case class and a hungry man single case class
3.1 Lazy Single Case classFo
