- Describe the difference between the way a class that implements the List interface stores and accesses elements and the way that aclass that implement the Map interface stores and accesses elements .Create a CircularArray class that supports an efficiently rotating array-like data structure. The class should, if at all possible, use a generic type (also known as a template) and support iteration using the for (Obj o: circularArray) notation.Which is true? a. A LinkedList offers faster element insertion than an ArrayList b. A List implements the LinkedList interface c. A LinkedList implements the ArrayList interface d. A LinkedList offers faster positional access than an ArrayList
- Create an implementation of a doubly linked DoubleOrderedList class. You will need to create a DoubleNode class, a DoubleList class, and a DoubleIterator classImplement a LinkedList class that stores integers using dynamic memory and a proper main program to test it. The following member functions need to be properly implemented and tested: 1. Default constructor. 2. Parmetrized Constructor. 3. Sum. 4. Average. 5. InsertAtHead. 6. InsertAtTail. 7. Delete. 8. Pop. 9. Circular. 10. Display. Sample answer is also provided.Answer for.Write a Python Code for the given constructor and conditions: Given Constructor: def __init__ (self, a) Pre-condition: Array cannot be empty. Post-condition: This is the default constructor of MyList class. This constructor creates a list from an array..
- Implement a CircularArray class that supports an array-like data structure whichcan be efficiently rotated. If possible, the class should use a generic type (also called a template), and should support iteration via the standard for (Obj o : circularArray) notation.I'm trying to understand LargeIntList classes for lists, I was wondering these statements or True or False? either or, can you please explain your answers? Thank you. Uses the “by copy” approach with its elements. Implements the ListInterface interface. Keeps its data elements sorted. Allows duplicate elements. Uses the LLNode class of the support package. Throws an exception if an iteration “walks off ” the end of the list. Throws an exception if an element is added when it is "full". Supports addition of elements at the front of the list, the end of the list, and anywhere in between. Can hold objects of any Java class. Has only O(1) operations, including its constructor. Provides more than one Iterator.There’s a somewhat imperfect analogy between a linked list and a railroad train, where individual cars represent links. Imagine how you would carry out various linked list operations, such as those implemented by the member functions insertFirst(), removeFirst(), and remove(int key) from the LinkList class in this hour. Also implement an insertAfter() function. You’ll need some sidings and switches. You can use a model train set if you have one. Otherwise, try drawing tracks on a piece of paper and using business cards for train cars.
- Question 7 The method(s) with signature(s) defined in the Comparator interface is/are: Question 11 To simplify list processing, a header node is defined as a placeholder node at the beginning of a list and a trailer node is defined as a placeholder node at the end of the list. When a list is empty, which statement is NOT correct? Question 18 True or False? When an object of class ArrayCollection represents an empty collection, its numElements variable is 0. Question 20 True or False? If N represents the number of elements in the collection, then the add method of the SortedArrayCollection clas Question 21 True or False? Our LBList class inherits from the ABList class.Create a template class for a dynamic 1D array. You can model your class off of our Stringclass or the dynamic list class. Changes from Stringclass: You won't need an end-of-string element in the array. The element type is now templated. Translation will no longer be necessary. operators - and -= 'might' now make sense (erase element(s)?). ... Show how useful your template array class is by creating arrays of short integers doubles Stringclass objects (static) Pointclass objects pointers to Pointclass objects (each allocated on the heap) — all in one test application. Make sure your test application is a good/thorough test of your class. (Your test application might utilize the applyand accumulatefunctions from lecture to facilitate testing. Also note how a typical template test application is structured — using templates to ease development.The JCF provides numerous ADTs. Write code to show how the JCF class ArrayList, LinkedList, and Iterator are used to maintain a grocery list. Verify list methods such as "create()", "add()", "get()", "remove()", "isEmpty()", "size()", "removeAll()" and exception handling.
