Instructions Write a program to test various operations of the class doublyLinkedList. Your program should accept a list of integers from a user and use the doubleLinkedList class to output the following: The list in ascending order. The list in descending order. The list after deleting a number. A message indicating if a number is contained in the list. Output of the list after using the copy constructor. Output of the list after using the assignment operator. An example of the program is shown below: Enter a list of positive integers ending with -999: 83 121 98 23 57 33 -999 List in ascending order: 23 33 57 83 98 121 List in descending order: 121 98 83 57 33 23 Enter item to be deleted: 57 List after deleting 57 : 23 33 83 98 121 Enter item to be searched: 23 23 found in the list. ********Testing copy constructor*********** intList: 23 33 83 98 121 ********Testing assignment operator*********** temp: 23 33 83 98 121 Your program should use the value -999 to denote the end of the…

Define a collection “ArrayList” to store the students' names. Use a loop to take 5 students’ names from the user and store them in the collection. Add two student names to the collection and remove the last name in the list. Insert a student name in third place in the collection. Sort the names alphabetically. Ask the user to enter a student name and search for it in the collection and prints the result as “Found” or “Not Found”. Print the whole collection using the enhanced for loop.   (java)
