Hi,
I am trying to write something like
public class A implements B<T implements C> {}
and
public abstract class M<I extends P> extends R<I extends P> implements Q<I extends P> {}
but I am getting errors like Multiple markers and syntax error on token extends, expected. Please let me know what is the correct way of doing this.
There is no implements keyword in generic bounds. It's only extends
Furthermore - you should specify the type parameter only in the class definition, and not in supertypes. I.e.
public class A<T extends C> implements B<T> {}
When you have interfaces in generics, you still have to use the extends keyword.
In your case, if you know what T will be :
public class A<T extends C> implements B<T> {}
If you don't and you simply have to implements B with a C type :
public class A implements B<C> {}
For the second part, once you've defined I you can use it as is in your other generic types :
public abstract class M<I extends P> extends R<I> implements Q<I> {}
