Re: triangle, rectangle and TwoDShape

Click to Expand / Collapse Quote originally posted by piers ...

I changed it in my rectangle class but I am still getting 0.0 when I run my driver class.

Do you ever call the calculateAre of Triangle and Rectangle? you should call calculateArea to actually calculate and assing new value to area e.g.

Java Syntax (Toggle Plain Text)
class TwoDShapeDriver
{
     public static void main (String []args)
     {
          Triangle t1 = new Triangle(44,55,"scalene");  
          t1.calculateArea();
          System.out.println(t1.toString());
 
 
          Rectangle r1 = new Rectangle(22,44);
          r1.calculateArea();
          System.out.println(r1.toString());
     }
}
class TwoDShapeDriver
{
     public static void main (String []args)
     {
          Triangle t1 = new Triangle(44,55,"scalene");  
          t1.calculateArea();
          System.out.println(t1.toString());

	
          Rectangle r1 = new Rectangle(22,44);
          r1.calculateArea();
          System.out.println(r1.toString());
     }
}
