Design the class unorderedSetType, derived from the class unorderedArrayListType, to manipulate sets. Note that you need to redefine only the functions insertAt, insertEnd, and replaceAt. If the item to be inserted is already in the list, the functions insertAt and insertEnd output an appropriate message, such as 13 is already in the set. Similarly, if the item to be replaced is already in the list, the function replaceAt outputs an appropriate message. Also, write a program to test your class.
- Unique Words Summary Specifications:You are tasked to implement an abstract data type class which takes in a given input file called input.txt, and processes, identifies and sorts all unique word instances found in the file. Sample InputHi hello hi good bye goodbye Bye bye good say Sample OutputBye Hi bye hello hi say The input.txt file is found along with the zip folder where this instructions file also came along with. Note: you are not allowed to use pythonic lists, and its methods and functions, and string methods. However the use of the file handling methods (read readlines and readline) are allowed for this project.Add the following operation to the class orderedLinkedList: void mergeLists(orderedLinkedList<Type> &list1, orderedLinkedList<Type> &list2); //This function creates a new list by merging the //elements of list1 and list2. //Postcondition: first points to the merged list // list1 and list2 are empty Consider the following statements: orderedLinkedList<int> newList; orderedLinkedList<int> list1; orderedLinkedList<int> list2; Suppose list1 points to the list with the elements 2 6 7, and list2 points to the list with the elements 3 5 8. The statement newList.mergeLists(list1, list2); creates a new linked list with the elements in the order 2 3 5 6 7 8, and the object newList points to this list. Also, after the preceding statement executes, list1 and list2 are empty. 2. Write the definition of the function template mergeLists to implement the operation mergeLists.Exercise 1• Create a class that sorts a list in ascending order. Make use of the Collections method sort• The list should be a list of Strings.• Test your code with {“Hearts”, “Diamonds”, “Clubs”, “Spades”}• Before and after the sort, use the implicit call to the list’s toString method to output the list contents. Exercise 2• Create a class with the same requirement as in Exercise 1, but the sort should be in descending order• Make use of the Comparator interface• Make use of the static collection method reverseOrder java
