- Write the following method that returns thesmallest element in an ArrayList:public static <E extends Comparable<E>> E min(ArrayList<E> list)Write the following method that returns an ArrayList from a set:public static <E> ArrayList<E> setToList(Set<E> s)Computer Science create a method +addToList(o:E):void that adds the object (o) to the ArrayList referenced by the instance variable list. create a method +removeFromBackOfList():E that removes the object at the back of the ArrayList and returns it.
- Write the following method that shuffles an ArrayList:public static <E> void shuffle(ArrayList<E> list)The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.LAB: Inserting an integer in descending order (doubly-linked list) Given main() and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insertInDescendingOrder() method to insert new IntNodes into the IntList in descending order.

True or False If N represents the number of elements in the list, then the index-based add method of the ABList class is O(N). True or FalseFile TesSLL.java contains a driver that allows you to experiment with these methods. Compile and run TestSLL, and play around with it to see how it works. Then add the following methods to the SinglyLinkedList class. For each, add an option to the driver to test it. Do this in incremental steps!! This means, implement and test the methods one at a time.
- Project Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order. Use the method signature: public static String[] reverse Words (String[] wordList) Example Input: Bird Cat Dog Elephant Output: Elephant Dog Cat BirdProject Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order. Use the method signature: public static String[] reverseWords (String[] wordList) Example Input: Bird Cat Dog Elephant Output: Elephant Dog Cat Birdjava program java method: Write a method replace to be included in the class KWLinkedList (for doubly linked list) that accepts two parameters, searchItem and repItem of type E. The method searches for searchItem in the doubly linked list, if found then replace it with repItem and return true. If the searchItem is not found in the doubly linked list, then insert repItem at the end of the linked list and return false. Assume that the list is not empty. You can use ListIterator and its methods to search the searchItem in the list and replace it with repItem if found. Do not call any method of class KWLinkedList to add a new node at the end of the list. Method Heading: public boolean replace(E searchItem, E repItem) Example: searchItem: 15 repItem: 17 List (before method call): 9 10 15 20 4 5 6 List (after method call) : 9 10 17 20 4 5 6
