Can I consider interface methods as abstract methods?

Question

I was thinking about that, and I had some doubts.

When I declare an interface, for example:

public interface MyInterface
{
   public void method1();
   public void method2();
}

Could these interface methods be considered abstract? What I mean is that the concept of an abstract method is:

An abstract method is a method that is declared, but contains no implementation.

So, could these methods be considered abstract? They are not "pure" abstract methods as I'm not using the abstract word, but conceptually, it looks like they are.

What can you tell me about it?

Thanks.
