An aggregation is a specialized form of Association where all object has their own lifecycle but there is ownership and child object can not belong to another parent object. A single teacher can not belong to multiple departments, but if we delete the department teacher object will not destroy.

What is composition in Java? It is a strong type of Aggregation. Child object does not have their lifecycle and if parent object deletes all child object will also be deleted.

Object cloning in Java is the process of creating an exact copy of an object. It basically means the ability to create an object with a similar state as the original object.

This method creates a new instance of the class of the current object and then initializes all its fields with the exact same contents of corresponding fields.

To object clone , the marker interface java. Cloneable must be implemented to avoid any runtime exceptions. One thing you must note is Object clone is a protected method, thus you need to override it. What is a copy constructor in Java? Copy constructor is a member function that is used to initialize an object using another object of the same class. Though there is no need for copy constructor in Java since all objects are passed by reference. Moreover, Java does not even support automatic pass-by-value.
