**What happens when you remove the entry from position 4 from a List?**Select one:a. All of theseb. The entry in the 4th position is returned (if there was a 4th entry)c. If the List has 3 or fewer entries, an IndexOutOfBoundsException is thrownd. If the List has 5 or more entries, the entries in positions 5 and up will move up 1 spot earlier to close up the gap vacated by removing the 4th entry

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)

I'm trying to understand LargeIntList (Large Integers) classes for lists, I was wondering these statements or True or False? either or, can you please explain your answers? Thank you. 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.
Create class Test in a file named Test.java. This class contains a main program that performs the following actions: Instantiate a doubly linked list. Insert strings “a”, “b”, and “c” at the head of the list using three Insert() operations. The state of the list is now [“c”, “b”, “a”]. Set the current element to the second-to-last element with a call to Tail() followed by a call to Previous()Then insert string “d”. The state of the list is now [“c”, “d”, “b”, “a”]. Set the current element to past-the-end with a call to Tail() followed by a call to Next(). Then insert string “e”. The state of the list is now [“c”, “d”, “b”, “a”, “e”] . Print the list with a call to Print() and verify that the state of the list is correct.
For example, suppose the word “robot” is found in lines 7, 18, 94, and 138. The dictionary would contain an element in which the key was the string “robot”, and the value was a list containing the numbers 7, 18, 94, and 138. Once the dictionary is built, you should prompt the user for a word. If the word is found in the dictionary, then print out all the lines on which they are found in ascending order. The code for the print out is provided in the stub code. A stub code is provided for you. If you do not see it, click the "Load default template" button. # The get_word_dict function returns a dictionary containing# the words from line_list as keys, and their line numbers# as values.def get_word_dict(line_list):# Create a line counter.count = 0 # Create a dictionary to hold the words.word_dict = {} # Step through the list of lines.#######Add you code below############# ####################################### Return the dictionary.return word_dict #####DO NOT CHANGE ANYTHING…
This will happen if you try to use an index that is out of range for a list.a. A ValueError exception will occur.b. An IndexError exception will occur.c. The list will be erased and the program will continue to run.d. Nothing—the invalid index will be ignored.
