ShallowCopy and Deepcopy

Difference between Shallow Copy and deep copy.

Shallow copy copy creates new object and copies references in the object and wont copy the referenced objects.

Eg: "X" is an object and having references to objects "A" and "B" .
Now object "X1" is created as shallow copy to object "X" . now X1 contains references to "A" and "B".
i.e both X and X1 are pointing to objects "A" and "B".If any non static variables present in "X" those are also copied directly bit-by-bit into "X1".

In deep copy "X1" contains references to "A1","B1" which are copies of "A"&"B".
