Sultan Qaboos University Department of Computer Science COMP2202: Fundamentals of Object Oriented Programming Assignment # 2 (Due 5 November 2022 @23:59) The purpose of this assignment is to practice with java classes and objects, and arrays. Create a NetBeans/IntelliJ project named HW2_YourId to develop a java program as explained below. Important: Apply good programming practices: 1- Provide comments in your code. 2- Provide a program design 3- Use meaningful variables and constant names. 4- Include your name, university id and section number as a comment at the beginning of your code. 5- Submit to Moodle the compressed file of your entire project (HW1_YourId). 1. Introduction: In crowded cities, it's very crucial to provide enough parking spaces for vehicles. These are usually multistory buildings where each floor is divided into rows and columns. Drivers can park their cars in exchange for some fees. A single floor can be modeled as a two-dimensional array of rows and columns. A…
JAVA CODE PLEASE THANK YOU Rectangle by CodeChum Admin A rectangle can be formed given two points, the top left point and the bottom right point. Assuming that the top left corner of the console is point (0,0), the bottom right corner of the console is point (MAX, MAX) and given two points (all "x" and "y" coordinates are positive), you should be able to draw the rectangle in the correct location, determine if it is a square or a rectangle, and compute for its area, perimeter and center point. To be able to do this, you should create a class for a point (that has an x-coordinate and a y-coordinate). Also, create another class called Rectangle. The Rectangle should have 2 points, the top left and the bottom right. You should also implement the following methods for the Rectangle: display() - draws the rectangle on the console based on the sample area() - computes and returns the area of a given rectangle perimeter() - computes and returns the perimeter of a given rectangle…

x = 3 + numbers[3]++; System.out.println(x); QUESTION 2: Class Rectangle has two data members, length (type of float) and width (type of float). The class Rectangle also has the following: //mutator methods void setlength (float len) } //B. length = len; H accessor methods float getLength() I return length; The following statement creates an array of Rectangle with size 2: Rectangle[] arrayRectangle= new Rectangle[2]; Is it correct if executing the following statements? What is the output? If it is not correct, write the correct one arrayRectangle. setLength (12.59); System.out.printin[rectangle Set.getLength()); arrayRectangle[1].setLength(4.15); System.out.println(arrayRectangle[1].getLength()): QUESTION 3: Use the following int array int[] numbers = { 42, 28, 36, 72, 17, 25, 81, 65, 23, 58} -Open file data.txt to write. to write the values of the array numbers to the file with the y numbers to get the values
Area of a rectangle = length * width Create a Class that calculates and prints out the area of a rectangle. Then write code that creates an object of this Class in which given the length and width, it calculates and prints out the area of a rectangle. Your output should look like this: Area of rectangle: 87
Part 3. arange Method Define a method in simpy named arange. Its purpose is to fill in the values attribute with range of values, like the range built-in function, but in terms of floats. It has three parameters in addition to self, the last being optional: 1. start - a float indicating the first value in the range 2. stop - a float that is not included in the produced range values 3. step - a float whose default value is 1.0 that indicates how to increase (or decrease) each subsequent item in the generated range. Unlike the built- in range function, this can be a fractional, float value. Step cannot be 0.0. Think carefully about what the value of step tells you about how to design your loop(s) for this method. Before any looping, you should assert step != 0.0 to be sure you avoid an infinite loop with an invalid argument. positive = Simpy([]) positive.arange(1.0, 5.0) print("Actual: ", positive, " - Expected: Simpy([1.0, 2.0, 3.0, 4.0])") fractional = Simpy([]) positive.arange (0.0,…

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…
