Expert's answer
public class RectangleDemo {


private class Rectangle {


private double height;
private double width;
private String color;

public Rectangle(double wid, double high){
height = high;
width = wid;
}

public Rectangle(){
height = 1;
width = 1;
color = "White";
}



public void setHeight(double high){
height = high;
}

public void setWidth(double wid){
width = wid;
}

public void setColor(String col){
color = col;
}


public double getArea(){
return height*width;
}

public double getPerimeter(){
return 2*(height + width);
}

public void getColor(){
System.out.println("Color is: " + color +"
");
return;
}

}
public class RectangleDemo {
public static void main(String[] args){
Rectangle box1 = new Rectangle();
Rectangle box2 = new Rectangle(4, 40);
Rectangle box3 = new Rectangle(3.5, 35.9);

String Color = "Red";

box1.setColor(Color);
box2.setColor(Color);
box3.setColor(Color);

box1.getColor();
box2.getColor();
box3.getColor();

System.out.println("The perimeter of the first box is: " + box1.getPerimeter() +
"
");
System.out.println("The perimeter of the second box is: " + box2.getPerimeter() + "
");
System.out.println("The perimeter of the third box is: " + box3.getPerimeter() + "
");

System.out.println("The area of the first box is: " + box1.getArea() + "
");
System.out.println("The area of the second box is: " + box2.getArea() + "
");
System.out.println("The area of the third box is: " + box3.getArea() + "
");
}
}
