8.2.1 Combining interfaces
New interaces can be created by combining two of more base interfaces. For example,
based on the previous example, we can add another interface which defines a
calcDifference() method:
interface NewCircuit
{
double r1 { set; get;}
double r2 { set; get;}
double calcParallel();
double calcSeries();
}
interface NewCircuit2
{
double calcDifference();
}
These interfaces can be merged with:
interface NewCircuitTotal : NewCircuit, NewCircuit2
{}
Then the class is derived with:
public class Circuit: NewCircuitTotal
{
private double res1, res2;
duction to .NET
Intro
public double r1
{
set { res1=value;}
get { return res1; }
}
public double r2
{
set { res2=value;}
get { return res2; }
}
public void Setr2(double r)
{
r2=r;
}
public double calcParallel()
{
return((r1*r2)/(r1+r2));
}
public double calcSeries()
{
return(r1+r2);
}
public double calcDifference()
{
return(r1-r2);
