Intro to programming using java, problem 9.1 The Rectangle Class, the bold is where I am getting the errors

package javaapplication3;

public class JavaApplication3 {

/** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here //UML Class Diagram /************************************************** * Rectangle * * ------------------------------------------------* * width: double * * height: double * * Rectangle() * * Rectangle(newWidth: double, newHeight: double) * * getArea(): double * * getPerimeter(): double * ***************************************************/

double width; double height;

Rectangle() { width = 1; height = 1; }

Rectangle(double newWidth, double newHeight) { width = newWidth; height = newHeight; }

double getArea() { return width * height; }

double getPerimeter() { return 2 * (width + height); } Rectangle rectangle1 = new Rectangle(4, 40);

Rectangle rectangle2 = new Rectangle(3.5, 35.9);

System.out.println(" Rectangle 1"); System.out.println("-------------"); System.out.println("Width: " + rectangle1.width); System.out.println("Height: " + rectangle1.height); System.out.println("Area: " + rectangle1.getArea()); System.out.println("Perimeter: " + rectangle1.getPerimeter());
