- 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.

Your program will draw a board with 64 squares using the traditional layout, next ask the user to choose a move, and then, depending on the user's choice, redraw the board with the selected chess piece and its valid moves. Please see the examples of valid moves of chess pieces and the traditional chess board layout below: At the beginning, your program should draw an empty chess board and prompt the user to enter a move: Welcome to the Chess Game! a b c d e f g h +---+---+---+---+---+---+---+---+8| | | | | | | | |8 +---+---+---+---+---+---+---+---+7| | | | | | | | |7 +---+---+---+---+---+---+---+---+6| | | | | |…arrow_forwardNOTE: JAVA language Write a program that asks the user for his first name and then prints it using a function/method called printName().
