Answer Posted / rajani nagandla
The Singleton is a useful Design Pattern for allowing only
one instance of your class.The Singleton's purpose is to
control object creation, limiting the number to one but
allowing the flexibility to create more objects if the
situation changes. Since there is only one Singleton
instance, any instance fields of a Singleton will occur
only once per class, just like static fields.
