Extending Interfaces
Interfaces can be extended as classes can be. Example :
interface base {
void baseMethod();
}
interface derived extends base // extending interface
{
void derivedMethod();
//void baseMethod(); automatically comes here
}
class baseClass implements derived {
public void baseMethod() {
System.out.println("from first interface");
}
public void derivedMethod() {
System.out.println("from second interface");
}
}
public class InterfaceExtend {
public static void main(String[] args) {
baseClass b = new baseClass();
b.baseMethod();
b.derivedMethod();
}
}
