The general form of a class that implements an interface is shown here:
class class-name : interface-name {
// class-body
}
To implement more than one interface, the interfaces are separated with a comma.
A class can inherit a base class and also implement one or more interfaces.
The name of the base class must come first in the comma-separated list.
The methods that implement an interface must be declared public.
public interface ISeries {
int getNext();
void setStart(int x);
}
class Sequence : ISeries {
int val;
public ByTwos() {
}
public int getNext() {
return val++;
}
public void setStart(int x) {
val = x;
}
}
