    Post Neeh help in task please

    Hi all,
    I need to define an abstract base type called Quadrilateral. Derived types Rectangle, Square and Parallelogram are based on this type. i need to write definitions of the public abstract class Quadrilateral along with the classes for the derived types according to fallowing table:


    Quadrilateral : Area = Abstract , toString()=name

    Rectangle: Area = length*width ,toString()=name, perimeter
    Square: Area = length * length, toString()=name, perimeter
    Parallelogram: Area =length * width ,toString()=name, perimeter

    Assume that the derived class name is used as the name and that the length and width are double values.
    Write a test harness that defines a object of each of these types, and prints out the name and area of a sample of each of the types.

    Thanks

    Do you have a question about how to complete your assignment?

    Given those hints and instructions the code almost writes itself.

    Almost is as good as ~1.6km.

    Doesn't quite roll of the tongue, though...

    Waidaminnit, are we talkling about the golden ratio 'phi' here? ((1+sqrt(5))/2); 'almost is as good as phi km' sounds a bit better and can be understood by us metric folks too ;-)
