Shallow copy is a bit-wise copy of an object. A new object is created that has an exact copy of the values in the original object. If any of the fields of the object are references to other objects, just the reference addresses are copied i.e., only the memory address is copied. deep copy copies all fields, and makes copies of dynamically allocated memory pointed to by the fields. A deep copy occurs when an object is copied along with the objects to which it refers.
Techopedia explains Shallow Copy. Shallow copy is similar to deep copy in the assignment of each member of an object to that of another object, but it differs in the manner in which the field of reference type is copied. Unlike in shallow copy where the reference is only copied, in deep copy, a new copy of the referred object is created.
