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());
     }
