PART B: JUnit Testing Write a Java program according to the following: Create a Multiple.java class. Create the following two static methods (with return type float): SquareRoot() and CubeRoot(). SquareRoot) method should take two arguments and return the float value at the end. CubeRoot() method should take three arguments and return the float value at the end. Create a test class with the name MultipleTest.java. In this class, import the following libraries at the top of this file import org.junit. Before; import org.junit. Test; import static org.junit.Assert.assertEquals; Create an object of Calculator.java class by writing the following code in CalculatorTest.java class: private Multiple multiple; @Before public void setup() {this.multiple new Multiple():) 4. Generate the JUnit test classes for both the methods one by one. Declare and initialize the required variables to pass those to the methods. Store the expected result in one of the variables and then compare it with the actual returned value of the specific function. After creating the required JUnit test cases for SquareRoot() and CubeRoot(), run all the test cases one by one. Check the output. All the test cases should be passed at the end

- Need a java code Create a class called SingleItem This class represents a bag that can hold any single type of object (decided at bag-creation time), and only one item of that type at a time. You may have a zero-parameter constructor if you want one, but you must have the following three features: Add a method called (addItem()) which returns whether or not it was successfully added Add a method which removes an item from the bag and returns it (deleteAnItem()), return null if there is no item Add a method to check if an item is in the bag (hasAnIteminTheBag()) which returns true or falsearrow_forwardWrite in Java and Include commentsarrow_forwardDon't give me AI generated answer or plagiarised answer.

Create an Array of Objects In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use. Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value. Invoke this method from main.arrow_forwardjava-Find the area of circle using method...

- In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member.

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 milesarrow_forward
