Implement the main method below in a class called Grade. The program should read integer points (use the Scanner class) and print the grade (“A”, “B”, “C”, “D”, or “F”) based on the final score associated with a student. Grades are classified as follows: Number of Points Final Grade Greater than or equal to 90 A Between 80 (inclusive) and 90 (exclusive) B Between 70 (inclusive) and 80 (exclusive) C Between 60 (inclusive) and 70 (exclusive) D Less than 60 F Restrictions/Assumptions Use the message “Enter final score” to prompt the user to enter the number of points. Use the Scanner class to read the number of points, i.e., Scanner sc = new Scanner(System.in); Use System.out.println(...) to print the final grade. Assume that the user correctly enters an integer score. Start with this code: import java.util.Scanner; public class Grade { public static void main(String[] args) { For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac)

You are working as a software developer on NASA's Mars Explorer robotic rover project. You need to implement some code to compute the surface area of the 3D, tube-shaped part shown below: a cylinder of radius r and height h (in units centimeters) with a hollowed-out center also in the shape of a cylinder with radius n and height h (also in cm). Both the outside and the inside of the tube will need to be coated in a thin layer of gold, which is why we need to know its surface area. Write code that will compute and print the total surface area of the shape. n esc r Examples: Inputs r = 10, n = 8.5, h = 22.5 r = 9.25, n = 6.8, h r = 4.15, n = 3.9, h = 11.7 = 12.16 X h Output Value 2789.7342763877364 1473.347264273195 604.4267185874082 2 3 80 F3 000 DO F4 ✓0 F5 完成时间:18:42 PNEUE MacBook Air F6 F7 DII F8 tv 8 F9 F10 F
JAVA SWINGI have definied a straight TUBE as: int rectWidth = 25; // replace 50 with the desired width of the rectangleint rectHeight = 200; // replace 200 with the desired height of the rectangleint rectX = (this.getWidth() - rectWidth) / 2;int rectY = (this.getHeight() - rectHeight) / 2;game.fillRect(rectX, rectY, rectWidth, rectHeight);I need L tube, which connects the straight tubes. How to define L tubes?
Write an improved version of the chaos . py program from Chapter 1 thatallows a user to input two initial values and the number of iterations, and then prints a nicely formatted table showing how the values changeover time. For example, if the starting values were . 25 and . 26 with 10iterations, the table might look like this: index 0.25 0.26----------------------------1 0 . 731250 0 . 7503602 0 . 766441 0 . 7305473 0 . 698135 0 . 7677074 0 . 821896 0 . 6954995 0 . 570894 0 . 8259426 0 . 955399 0 . 5606717 0 . 166187 0 . 9606448 0 . 540418 0 . 1474479 0 . 968629 0 . 49025510 0.118509 0 . 974630
Given main(), complete the Car class (in file Car.java) with methods to set and get the purchase price of a car (setPurchasePrice(), getPurchasePrice()), and to output the car's information (printInfo()). Ex: If the input is: 2011 18000 2018 where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, the output is: Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770 Note: printInfo() should use three spaces for indentation CarValue.java import java.util.Scanner;import java.lang.Math; public class CarValue {public static void main(String[] args) {Scanner scnr = new Scanner(System.in);Car myCar = new Car();int userYear = scnr.nextInt();int userPrice = scnr.nextInt();int userCurrentYear = scnr.nextInt();myCar.setModelYear(userYear);myCar.setPurchasePrice(userPrice);myCar.calcCurrentValue(userCurrentYear);myCar.printInfo();}} Car.Java public class Car {private int modelYear; // TODO: Declare purchasePrice field…
Implement the following in the .NET Console App. Write the Bus class. A Bus has a length, a color, and a number of wheels. a. Implement data fields using auto-implemented Properies b. Include 3 constructors: default, the one that receives the Bus length, color and a number of wheels as input (utilize the Properties) and the Constructor that takes the Bus number (an integer) as input.
Using the Card.java class file, write a program to simulate a Deck of Cards. See Programming Project 8.7 (PP 8.7) from page 403 of your textbook (or view the attached image) for a description of what your program needs to do. Note that although the book description of the problem states that you should write the Card class, I do not want you to do that. You must use the Card file exactly as it is provided (NO modifications) and only write the DeckOfCards and Driver classes. public class Card{public final static int ACE = 1;public final static int TWO = 2;public final static int THREE = 3;public final static int FOUR = 4;public final static int FIVE = 5;public final static int SIX = 6;public final static int SEVEN = 7;public final static int EIGHT = 8;public final static int NINE = 9;public final static int TEN = 10;public final static int JACK = 11;public final static int QUEEN = 12;public final static int KING = 13; public final static int CLUBS = 1;public final static int DIAMONDS =…
There are three main operations on rectangles: intersection, union, and difference. Among them, only intersection is guaranteed to return another rectangle. In general, the union of two rectangles is... two rectangles, and the difference between two rectangles is ... a whole lot of rectangles, as we will see. We let you implement rectangle intersection. Of course, the intersection is defined only if the rectangles have the same number of dimensions. The intersection is computed by taking the intersection of the intervals of the two rectangles for corresponding dimensions. If one of the intervals is empty, you should return None. [] # @ title Rectangle intersection def rectangle_and(self, other): if self.ndims != other.ndims: raise TypeError("The rectangles have different dimensions: {} and {}".format( )) self.ndims, other.ndims ### YOUR SOLUTION HERE Rectangle. _and_ = rectangle_and [ ] r1 = Rectangle((2, 3), (0, 4)) r2 = Rectangle((0, 4), (1, 3)) draw rectangles (r1, r2) draw…
