An immutable object is initialized by its constructor only, while a singleton is instantiated by a static method. A set of functions (or static methods) which manipulate some shared mutable state constitute a singleton. This implies that every mutable member of a singleton collection is itself a singleton.

Singleton object will have only one object and multiple states and Immutable object will have each new object with each time the state is changed.
