Answer 1

You have to use the override keyword. An override can't be virtual. You're not inheriting from the Draw class, you're implementing the IDraw interface.

Answer 2

Class Brush and class Spray should inherit from the Draw class and override the StartDraw() method.

Answer 3

Yea you're right ChaoticDawg

Many thanks

Answer 4

ChaoticDawg, yes you're right but even when I save the changes, it doesn't override the StartDraw() method
