What is shallow and deep copy?

Shallow Copy stores the references of objects to the original memory address. Deep copy stores copies of the object’s value. Shallow Copy reflects changes made to the new/copied object in the original object. … Deep copy stores the copy of the original object and recursively copies the objects as well.

How do you distinguish between copy copy () and copy Deepcopy ()?

A shallow copy constructs a new compound object and then (to the extent possible) inserts references into it to the objects found in the original. A deep copy constructs a new compound object and then, recursively, inserts copies into it of the objects found in the original.

What does a shallow copy mean?

A shallow copy means constructing a new collection object and then populating it with references to the child objects found in the original. In essence, a shallow copy is only one level deep. The copying process does not recurse and therefore won’t create copies of the child objects themselves.

What is a deep copy of an object?

Deep copy is a process in which the copying process occurs recursively. It means first constructing a new collection object and then recursively populating it with copies of the child objects found in the original. In case of deep copy, a copy of object is copied in other object.
