I have a Linked List and I’m trying to create a copy of another Linked List and this copy is a deep copy because the element type is char. Due to the complexity of linked lists, I’ve tried not to use the add method. My code is shown below. Also I want to recursively add … Read more
Because python passes lists by reference This means that when you write “b=a” you’re saying that a and b are the same object, and that when you change b you change also a, and viceversa A way to copy a list by value: If the list contains objects and you want to copy them as … Read more
Yes, you should iterate over 2D boolean array in order to deep copy it. Also look at java.util.Arrays#copyOf methods if you are on Java 6. I would suggest the next code for Java 6:
E0_copy is not a deep copy. You don’t make a deep copy using list(). (Both list(…) and testList[:] are shallow copies.) You use copy.deepcopy(…) for deep copying a list. See the following snippet – Now see the deepcopy operation
Cloning the objects before adding them. For example, instead of newList.addAll(oldList); Assuming clone is correctly overriden inPerson.
Shallow copies duplicate as little as possible. A shallow copy of a collection is a copy of the collection structure, not the elements. With a shallow copy, two collections now share the individual elements. Deep copies duplicate everything. A deep copy of a collection is two collections with all of the elements in the original … Read more
