public class Rectangle {

  private double width;
  private double height;
  public Rectangle() {
    this.width = 20;
    this.height = 20;
  public Rectangle(double width, double height) {
    this.width = width;
    this.height = height;
  public double getArea() {
    return width*height;

public double getWidth() {
return width;
public double getHeight() {
return height;


Here is the rectangle class. The rectangle class has the width and height fields. It has a constructor that takes in no parameters so when you call the constructor with no parameters it will set it to whatever you want to default to be. Also there is a rectangle constructor that takes in the width and height and sets the fields equal to that. Then there is the simple getArea method that returns the area of the rectangle. As for get parameters I think for ease you would want to make a getWidth and getHeight methods.
