Write a class named TestScores. The class constructor should accept an array of test scores as its argument. The class should have a method that returns the average of the test scores. If any test score in the array is negative or greater than 100, the class should throw an "IllegalArgumentException". Demonstrate the class in a program

. Protected variables coth Task 1.1: Base Animai Create Animal Class with 3 protected attributes: • name - String • type-String • nocturnal - boolean • 4 public void Methods: • printInfo-should print: " is a(n) ." • printSleepInfo-should print: "s sleep during day." or "s sleep during night." • printRoam - should print: " walks around." • printFeed method - will implement in subclasses ● Subclass Owl: Constructor takes in name as argument and sets the attributes: • Type should be "Owl", nocturnal should be true and name is given as the argument ia printFeed method: • Should print "You give some mice." Overriding roam method: • Should print " flies around." Subclass Monkey: • Similar constructor: • Type should be "Monkey", nocturnal should be false and name is given as the argument printFeed method: Should print "You give some bananas." Create another public method called printClimb: Should print " climbs a tree!" Overriding roam method of owl as owls fly Animal printInfo():void…

a- Write a class definition for Student containing the following instance variables and methods: b- Create an object of this class c- Call the method to calculate and set average_test d- Print average test self. name self. test1 self. test2 self. average test A constructor to accept name, test1 and test2 as parameters and assign them to instant variables. A method to calculate and set averave test (each test worth 50%) A method to get average_test

Do this program in java programming language only and also make one student class,or methods in this program or please don't use array.

Create a second test class called TicketTest to test that a Ticket object isconstructed correctly when provided reasonable input.a. Write a test method that calls the following constructor with valid arguments:Ticket(Passenger p, Seat s, double price)Before you create the Ticket object:i. Use the wizard to generate the TicketTest classii. Add a test method to the class.iii. In the test method, create a Passenger object. The default constructorof the Passenger class generates a valid name “T. B. A.”, so either ofthe following statements instantiate a Passenger:Passenger passenger = new Passenger();Or:Passenger passenger = new Passenger(new PassengerName(“Mary”, “I”, “Worth”));iv. Create a Seat object.The Seat class has no explicit constructor so you must use the implicitdefault constructor and then call seat.setRow(int i) andseat.setLetter(char c) to specify a specific seat.Unit Testing with JUnitv. Create the ticket object, providing the passenger object, seat object and the price as a…

Write a class method named countOccurences that returns the number of times a particular integer occurs in an array of integers. The integer and the array will both be parameters.

//Todo write test cases for SimpleCalculator Class // No need to implement the actual Calculator class just write Test cases as per TDD. // you need to just write test cases no mocking // test should cover all methods from calculator and all scenarios, so a minimum of 5 test // 1 for add, 1 for subtract, 1 for multiply, 2 for divide (1 for normal division, 1 for division by 0) // make sure all these test cases fail public class CalculatorTest { //Declare variable here private Calculator calculator; //Add before each here //write test cases here }

javacoding please thank you!

Write an application (including algorithm) that uses a class called “Book” (seedetails below). The application must perform the following tasks. Create an array of “Book” objects (i.e., array must be able to store 2books). Create 2 “Book” objects initialized as follows.o title = “C++ Textbook”; Author = “Pete Parker”; Publisher =“Cengage”, ISBN = “0123456789”; subject = “Computer Programming”;o title = “Java Textbook”; Author = “Bruce Wayne”; Publisher = “McGrawHill”, ISBN = “9876543210”; subject = “Computer Programming”; Add the two books to the array.o Assume the two publishers have merged into a new company called“BookConglomerate”. Use a loop to create statements to modify thepublisher field with the new publisher name. Display the following information for both bookso Book Title (i.e., “C++ Textbook” or “Java Textbook”)o Authoro Publishero ISBNo SubjectThe Book class must contain the following. Constructor with parameters that initialize all instance variables title, author,…

3- Create a class named Player with a default name as "player", a default level as 0, and a default class type of "fighter". Feel free to add any other attributes you wish! Create an instance method in the Player class called attack that takes another player as a parameter. This function should compare the level of the two players, and return whether the player won, lost, or tied. Finally create a loop that allows the user to input a name and a class type for two players; the level of both players should be determined at random (between 1 and 99). Print out the name and attributes of each player, and have the first player attack the second. Print whether the player won, lost, or tied. Ask if the user wants to try again. (Python code)
