## Annotation Type Override

-     @Target(METHOD)
      @Retention(SOURCE)
      public @interface Override

  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.
