Create a project in Java and add the class Rectangle
attached is a picture of the basic code for the class Rectangle.
public class RectangleTest {
public static void main(String[] args) {
// Do the following, one statement for each!
// 1) Declare an object of Rectangle, call it englishBook, of length 5 and width 3.2
// 2) Print values: length, width, and area
// you must call the method toString() of class Rectangle
// 3) Declare an object of Rectangle, call it mathBook, do not send any arguments
// 4) Assign the value 4.1 to the width of the mathBook.
//5) Assign the the length of the englishBook to the length of the mathBook.
// 6) Print values: length, width, and area of the mathBook
// DO NOT call the toString method of class rectangle
// 7) Increase the current width of the englishBook by 2.5
// 8) Print values of the englishBook: length, width, and area
// which one is better using the toString method of class rectangle or Not using it?
