| Ans. Step 1 - We can create a Registry Class having Map of all created objects as key and References list as value. Step 2 - Whenever we create an object , we should update the Registry in the constructor to add the new object. Step 3 - Whenever we assign a new reference to the object , we need to update the entry in Map. Similarly if the reference get's removed ( end of scope etc ), we need to remove the entry of reference from the list. Step 4 - We can have threaded code to monitor the Map to see if any object looses all it's references and should call the method to destroy object and clean the memory. | ||||
