Indicates that a method declaration is intended to override a
method declaration in a supertype. If a method is annotated with
this annotation type compilers are required to generate an error
message unless at least one of the following conditions hold:

  • 
The method does override or implement a method declared in a
supertype.

  •  The method has a signature that is override-equivalent to that of any public method declared in Object.
