8.2 Extending Interfaces
An interface can extend another interface, similarly to the way that a class can extend another class.
The extends keyword is used to extend an interface, and the child interface inherits the methods of the parent interface.
this is achieved using the keyword extends as shown below:
public class C extends A implements B {
//trying to override doSomthing…
public int myMethod(int x) {
return doSomthingElse(x);
}
}
Example
interface ItemConstants
{
int code=2015;
string name=”Akshay”;
}
interface Item extends ItemConstants
{
void display();
}
