//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 }
Instructor note: This lab is part of the assignment for this chapter. This lab uses two Java files, LabProgram.java and SimpleCar.java. The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 miles
Task 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. */ }

Modify the student class presented in this chapter as follows. Each student object should also contain the scores for three tests. Provide a constructor that sets all instance values based on parameter values. Overload the constructor such that each test score is assumed to be initially zero. Provide a method called setTestScore that accepts two parameters: the test number (1 through 3) and the score. Also provide a method called getTestScore that accepts the test number and returns the appropriate score Provide a method called average that computes and returns the average test score for this student. Modify the toString method such that the test scores and average are included in the description of the student. Modify the driver class main method to exercise the new Student methods. (Java)

Case Problem 1 - In previous chapters, you developed classes that work with catering event information for Carly’s Catering. Now modify the Event and EventDemo classes as follows: Modify the Event class to include an integer field that holds an event type. Add a final String array that holds names of the types of events that Carly’s caters—wedding, baptism, birthday, corporate, and other. Include get and set methods for the integer event type field. If the argument passed to the method that sets the event type is larger than the size of the array of String event types, then set the integer to the element number occupied by other. Include a get method that returns an event’s String event type based on the numeric event type. To keep the EventDemo class simple, remove all the statements that compare event sizes and that display the invitation Strings. Modify the EventDemo class so that instead of creating three single Event objects, it uses an array of three Event objects. Get data for…
Novice: How can i access a main class objects from outside the function? / Better Alternative? If i have 4 Student objects how can i print the information for the specific object given one parameter about the class, like the students Idnumber. What i came up with was making a checkId void function that takes the user input and runs an if else chain checking if the Id belongs to student 1-4 then printing the details of that classes object with the void function print. ideally i would want the if-else chain in the checkId function to call the print( student1-4) class object but im not sure how to properly do that. i dont think this is the best way to go about it, if you have any recommendations or alternatives please help me out.
#this is a python program #topic: OOP Design a class Joker with parameterized constructor so that the following line of code prints the result shown in the output box.

1) Create a "Car" class that keeps car ids and prices. And create a "Galleries" class that holds the car list for a particular gallery. In this class there should be methods for get / set and print for car name, car number and car list. Adding / Removing Cars to the List in This Class should have methods. And create another method to find and print the IDs of Cars with Car Segment equal to X. (print (X)). Car Prices are as follows according to the segments. 0-19999 -> Z20000-29999 -> Y30000-44999 -> T45000-100000 -> P Apply the Car list using "Single Linked List"(Node, newNode, head). The program should be written in JAVA.
Please do P1 by redefining and using the student.py code. Strictly use the student.py code, you can change and add some code but you have to use it to create P1. Thanks a lot! P1: Add three methods to the Student class that compare two Student objects. One method should test for equality. A second method should test for less than. The third method should test for greater than or equal to. In each case, the method returns the result of the comparison of the two students’ names. Include a main function that tests all of the comparison operators. ***student.py*** """File: student.pyResources to manage a student's name and test scores.""" class Student(object): """Represents a student.""" def __init__(self, name, number): """All scores are initially 0.""" self.name = name self.scores = [] for count in range(number): self.scores.append(0) def getName(self): """Returns the student's name.""" return self.name def…
