What is Shallow copy
Answers
Shallow clone is a copying the reference pointer to the object, which mean the new object is pointing to the same memory reference of the old object. The memory usage is lower.
Original java object obj

The shallow copy is done for obj and new object obj1 is created but contained objects of obj are not copied.
Shallow copy object obj1

It can be seen that no new objects are created for obj1 and it is referring to the same old contained objects. If either of the containedObj contain any other object no new reference is created.   Your Comment
