8.1 Introduction
This module covers the key elements of arrays, indexers and collections. It covers:
• Interfaces.
• Constructors.
• Destructors.
• Static and instance members.
• Practical example.
8.2 Interfaces
An interface is an alternative method of creating an abstract, but it does not contain
any implementation of the methods, at all. It provides a base class for all the derived
classes. For example, in Figure 8.1 we have a circuit which can either have a series or
a parallel resistance.
Series circuit: R T
= R 1
+ R2
Parallel circuit:
R1
⋅ R2
R T
=
R + R
