This lab was designed to reinforce programming concepts from this lab, you will practice:
Declaring and initializing ArrayList.
Add elements to the Arraylist.
Display the content of the ArrayList.
Write a class name PhoneBookEntry that has fields for a person’s name and phone number. The class should have a constructor and the appropriate accessor and mutator methods. Then write a program that creates at least 5 PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.
This is the question I am stuck on -
A. Create a CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Create a Student class containing an ID number and an array of five CollegeCourse objects.
Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4). Next, create a set method that sets the value of one of the Student’s CollegeCourse objects; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4).
B. Write an application that prompts a professor to enter grades for five different courses each for 10 students. Prompt the professor to enter data for one student at a time, including student ID and course data for…

- You will need to use at least 1 additional class other than the class with the main method. Perhaps the class would be how you instantiate each character for the array? The class needs to contain at least 3 different private members (variable/attribute) and public getter and setter properties for those members. These could be name, points, whether the character is good or evil, etcarrow_forwardTask 1:The first task is to make the maze. A class is created called Maze, in which a 2D array for the maze is declared. Your job is to implement the constructor according to the given javaDoc. When you completed this task, write a set of Junit test case to test your code.As you probably noticed, the maze is defined as a private variable. The second job for you is to write an accessor(getter) method that returns the maze. Other information about what is expected for this method is given in the starter code. public class PE1 { MazedogMaze; /** * This method sets up the maze using the given input argument * @param maze is a maze that is used to construct the dogMaze */ publicvoidsetup(String[][]maze){ /* insert your code here to create the dogMaze * using the input argument. */ }arrow_forwardUrgent Requirement: There will one question related to ArrayList class similar to the following question.

- Create a new class in the practicum1 package named ArrayUtilities. Write a method in the class that meets the following requirements: - It should be named "arrayToString" - It should declare a parameter for an int array. - It should return a String in the same format as the example above, e.g. "[1, 2, 3]". If the array is length 0, you should return the string "[]". - It should NOT use the Arrays.toString() method - you should create and return the string yourself. - You may receive a warning from IntelliJ about using string concatenation. You may ignore it. Write a main method to test your method by calling it with one or more small arrays and printing the string(s). Example output: [] [1, 2, 3] [2, 3, 5, 7, 11, 13]arrow_forwardyou created a Card class that represents a standard playing card. Use this to design and implement a class called DeckOfCards that stores 52 objects of the Card class using an array. Include methods to shuffle the deck, deal a card, return the number of cards left in the deck, and a toString to show the contents of the deck. The shuffle methods should assume a full deck.Create a separate driver class that first outputs the populated deck to prove it is complete, shuffles the deck, and then deals each card from a shuffled deck, displaying each card as it is dealt along with the number of cards left in the deck.

- The UnsortedTableMap class is located in the maps folder. In the attachment, you will find a partially implemented class called UnsortedMapOfLists, which extends UnsortedTableMap. The values associated with the keys in UnsortedMapOfLists are arrays. So you have an array with each key. Off course you can save an array in the value of UnsortedTableMap class without the class we are going to develop, but our class makes this easier, as it allows using a syntax like this: myMap["somekey", 1] to reach element at index 1 in the array associated with key "somekey". I already implemented methods __setitem__ and __getitem__. Your task is to: implement method __delitem__ . Deletion will be performed for an element in the array. If index is not given, delete the array associated with the key. implement a function (not a method in the class) to swap the arrays associated with two given keys. Add the required comment in method __getitem__. implement a main to verify that your code is working…arrow_forwardWrite a program called ArrayOfStudents that displays information of three students. You need to use array of objects. Each element in the array need to be initialized using a constructor. Each Student will have (name, id and Specialization). The Program will display the student information by invoking the method showStudentData(). Challenge: Can You modify the program to allow the user to enter the number of students stored in the array of objects, and ask the user to insert the details of each student.arrow_forwardIn this lab assignment you need to implement the method named middleValue, in a program named ArrayOps.java. The method accepts an array of integer values as a parameter, and returns the value in the middle of the array. For instance, if an array contains five elements, then the third element would be the middle element to be returned. However, if the array contains six elements, both the third and fourth values could be considered to be the middle elements. In this case, only return the first middle value, namely, the third element of the array. Complete the method middleValue, and test the correctness of your method in main(). Particularly, you should create two arrays (arbitrary values), one array with odd length, and the other with even length, and print out the middle values of these two arrays.arrow_forward
