continue from first question, Client class:The client program will allow entry of these data for several different student into an ArrayList and then perform some analysis and queries.Your client class (program) will provide the user with a menu to perform the following operations. You will also need to load the information of the students from a CSV file (student.csv) before displaying the menu. You only need one ArrayList and one menu for this. For the csv file, your first item can be U or G to differentiate whether the entry is creating a UndergraduateStudent object, or a GraduateStudent object. You can then decide how you want other data to be listed in the csv file. You should specify clearly in your documentation the data format of the CSV files used in this assignment.1. Quit (exit the program)2. Add (to the ArrayList) all the marks information about an undergraduate or graduate student by reading it from another CSV file. Your program will ask for the file name.3. Given student…

Q8. Write a declaration of a private field named department that can hold an ArrayList. The elements of the ArrayList are of type Student. Write an assignment to the department variable to create an appropriate ArrayList object. Q9. (A) If a collection stores 20 objects, what value would be returned from a call to its size method? (B) Write a method call using get to return the fifth object stored in a collection called department. Q10. Write a method call to add the object held in the variable student1 to a collection department files.

Java Objects and Linked Data: Select all of the following statements that are true. The Java Class Library's class ArrayList implements the LinkedList interface. In Java, when one reference variable is assigned to another reference variable, both references then refer to the same object. In Java, the "equals"-method that any object inherits can be overwritten to compare objects field by field.
Scrabble Help: The file dictionary.txt contains all of the words in the Official Scrabble Player's Dictionary, Second Edition. Note: this list contains some offensive language. Write a class, WordLists, in Java that generates useful word lists for scrabble players using this list. Your class should contain the following methods: WordLists(String fileName): a constructor that takes the name of the dictionary file as the only parameter. lengthN(int n): returns an ArrayList of all length n words (Strings) in the dictionary file. endsWith(char lastLetter, int n): returns an ArrayList of words of length n ending with the letter lastLetter containsLetter(char included, int index, int n): returns an ArrayList of words of length n containing the letter included at position index. So for example the word "cannon" would be on the list returned by containsLetter('o',6,4) because it contains the letter 'o', at index 4, and is length 6. multiLetter(int m, char included): returns an ArrayList of…
1) What is one main disadvantage of an ArrayList? 2) Write a Java statement to create an ArrayList called list to hold 25 integers. 3) What is the type of the ArrayList defined in question number 2? 4) Write a for loop to initialize the objects in the ArrayList created in question number 2 above to -1.
How do I add several objects to an ArrayList in JAVA using a loop?
Arrays: create an array of a given type and populate its values. Use of for loop to traverse through an array to do the following : to print the elements one by one, to search the array for a given value. ArrayList: create an ArrayList containing elements of a given type . Use some of the common ArrayList methods to manipulate contents of the ArrayList. Write methods that will take an ArrayList as its parameter/argument ; and/or return an ArrayList reference variable as its return type. Searching for an object in an Array: Loop through the ArrayList to extract each object and to check if this object’s attribute has a given value. Explain how and why interfaces are used in Java Collection Framework. Explain the major differences between a Stack and a Queue. Be able to use stack and queue methods. What is meant by O(N) notation? Express the complexity of a given code using the O(N) notation.
To 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…
Define a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step…
