Why is there no @Implements annotation in Java?

Question

I found the @Override annotation very useful, overriding some super class methods in my derived classes. Basically, the compiler detects flaws in my program, which is always good. But why is there no @Implements annotation in Java?

Answer 1

Because you are using @Override for methods defined by interfaces.

(Yes, you are "implementing", not "overriding" ... but @Override used for both)

Answer 2

With Java 6, you can use @Override for class methods that implement methods defined in interfaces

Answer 3

To implement the interface, we use implements , and if any method exists in this interface, we override these methods to ensure implementation.

Thus, there is only the @Override annotation, because in both cases (class or interface) we always override.

Answer 4

To implement an interface, a keyword already exists: implements . but there is no such keyword to override. @Override not a keyword, but works similarly.
