Private Constructor mainly used for the single tone object. If in your application you want to use a class object unchangeable. suppose after login you want to create a user object and that will not changeable after login then we can go for the private constructor. and sometimes we work with List of objects and the items of the list change on runtime those type of scenario we will go for Collection.

Some reasons where you may need private constructor: The constructor can only be accessed from static factory method inside the class itself. Singleton can also belong to this category. A utility class  that only contains static methods.
