How to create Singleton design pattern?

To create the singleton class, we need to have static member of class, private constructor and static factory method.

• Static member: It gets memory only once because of static, itcontains the instance of the Singleton class.
• Private constructor: It will prevent to instantiate the Singleton class from outside the class.
• Static factory method: This provides the global point of access to the Singleton object and returns the instance to the caller.
