Area Class

Write a class that has three overloaded static methods for calculating the areas of the following geometric shapes:

  • circles
  • rectangles
  • cylinders

Here are the formulas for calculating the area of the shapes.

Area of a circle: Area = πr2
Where π is Math.PI and r is the circle’s radius
Area of a rectangle: Area = Width × Length
Area of a cylinder: Area = πr2h
Where π is Math.PI, r is the radius of the cylinder’s base, and h is the cylinder’s height

Because the three methods are to be overloaded, they should each have the same name, but different parameter lists. Demonstrate the class in a complete program.

Charge Account Validation Using Java programming Create a class with a method that accepts a charge account number as its argument. The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845    4520125    7895122    8777541    8451277    13028508080152    4562555    5552012    5050552    7825877    12502551005231    6545231    3852085    7576651    7881200    4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.
Shape Classes Design classes Square, RightTriangle , and Triangle that encapsulate three geometric shapes. Each class should implement a method void draw (int x, int y) that “draws" a square, a right triangle, or an equilateral triangle (a triangle with three equal sides), respectively. See Figure 2. The parameters x and y specify the relative position of the figure: y lines down and x spaces acro from the current position of the screen cursor. The instance variables of each class are: int rows , the number of rows that comprise the figure, and char character , the keyboard character used for drawing the figure. Each shape of Figure 2 consists of five rows. The drawing characters are *** for the square, %' for the right triangle, and #' for the equilateral triangle.

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…
