Create a DeleteDuplicatesclass which consists of a deleteDuplicates method which takes the nums list as its parameter.
Implement the deleteDuplicates method:
Check if the input list is null or empty, and return an empty list if so.
Initialize a pointer i to keep track of the unique elements.
Use a for loop to Iterate through the list using another pointer j which starts at j=1 and goes until j=nums.size();
If the current element at j is not equal to the previous element at i using !nums.get(i).equals(nums.get(j), increment i and set the current element at j to the new position at i using nums.set(i, nums.get(j)).
After the for loop ends, return the sublist from the beginning to i + 1, as this will contain all unique elements.
Call the deleteDuplicates method with the sample list as argument:
Call the deleteDuplicates method and pass the nums list as argument
Store the result in a variable result
Print the result to the console.
Input: [1, 1, 2, 3, 3,…
Two objects of the same class, say "mylnstance1" and "mylnstance2",
are declared in a program as a collection of some type (say an ArrayList). mylnstance1 is initialized but mylnstance2 is not.
Then mylnstance1 is copied to mylnstance2. If the copy is performed as
a
copy, two collections exist after the copy but the two collections share all the same elements.

- Use the ArrayList class Add and remove objects from an ArrayList Protect from index errors when removing Practice with input loop Details: This homework is for you to get practice adding and removing objects from an ArrayList. The Voter class was used to create instances of Voters which held their name and a voter identification number as instance variables, and the number of instances created as a static variable. This was the class diagram: The constructor takes a string, passed to the parameter n, which is the name of the voter and which should be assigned to the name instance variable. Every time a new voter is created, the static variable nVoters should be incremented. Also, every time a new voter is created, a new voterID should be constructed by concatenating the string “HI” with the value of nVoters and the length of the name. For example, if the second voter is named “Clark Kent”, then the voterID should be “HI210” because 2 is the value of nVoters and 10 is the number…arrow_forwardImport the ArrayList and List classes from the java.util package to create a list of phone numbers and also import the HashSet and Set classes from the java.util package to create a set of unique prefixes. Create a class called PhoneNumberPrefix with a main method that will contain the code to find the unique prefixes. Create a List called phoneNumbers and use the add method to add several phone numbers to the list. List<String> phoneNumbers = new ArrayList<>(); phoneNumbers.add("555-555-1234"); phoneNumbers.add("555-555-2345"); phoneNumbers.add("555-555-3456"); phoneNumbers.add("444-444-1234"); phoneNumbers.add("333-333-1234"); Create a Set called prefixes and use a for-each loop to iterate over the phoneNumbers list. For each phone number, we use the substring method to extract the first 7 characters, which represent the prefix, and add it to the prefixes set using the add method. Finally, use the println method to print the prefixes set, which will contain all of…arrow_forwardYou are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework.

- Java with screen shot pleasearrow_forwardTo demonstrate working with ArrayLists, we will be working with four source files: a Dessert class, two classes that extend Dessert called IceCream and Cake, and a TestDessert class. The TestDessert class contains a main() method that declares an ArrayList to hold Dessert objects. This ArrayList is referenced by the variable named "list". Examine TestDessert's main() method and notice the four comments. You are to implement code that accomplishes the tasks described in each step. For step 1, you are to populate the ArrayList with 10 IceCream and Cake objects. These objects should be inserted into the ArrayList at random. This means each run of the program should produce an ArrayList with different proportions of IceCream and Cake objects. After this operation, the ArrayList should contain 10 total objects (IceCream and Cake objects). Display the ArrayList after the operation. For step 2, if the first and last dessert in the ArrayList are different (one is IceCream and the other is…arrow_forwardThe 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.arrow_forward
- A deque (pronounced “deck”) is a list-based collection that allows additions and removals to take place at both ends. A deque supports the operations addFront(x), removeFront( ), addRear(x), removeRear( ), size( ), and empty( ). Write a class that implements a deque that stores strings using a doubly linked list below. Demonstrate your class with a graphical user interface that allows users to manipulate the deque by typing appropriate commands in a JTextField component, and see the current state of the deque displayed in a JTextArea component. Consult the documentation for the JTextArea class for methods you can use to display each item in the deque on its own line. ########################################################################################################################## import java.util.Objects; public class DoublyLinkedList<E> {Node head;DoublyLinkedList() {head = new Node(null, null, null);} /** Appending the first item in the list **/public Node addFirst(E…arrow_forwardJava programming Do the same question with List Array Write a method with the name "eraser" that will get two arguments: “maparr_plants" (Map array of objects of a kind of class Plant), and "eraselist" (One dimensional array of integers).

The most prominent feature of ArrayList is that it expands automatically as elements are added to it. It can be traversed using a for loop, for each loop and iterator( which you have implemented in Lab 2).In this lab you are going to implement your own ArrayList and its functionalities.Task 1.1: Create a class Generic ArrayList with attributes.Task 1.2: Implement a constructor for your ArrayList class.Task 1.3: Implement add() method for adding elements to ArrayList. Remember, ArrayList adds elements dynamically. It doesn't depend on user defined size.Task 1.4: Implement remove() method for removing an element from a specific index. Remember, ArrayList stores elements in a consecutive sequence. If an element is removed from middle you have to re-adjust the elements in the correct sequence.
