All annotation types automatically extend the Annotation interface.
Annotation is a super-interface of all annotations.
It overrides hashCode( ), equals( ), and toString() defined by Object.
It defines annotationType( ), which returns a Class object that represents the invoking annotation.
When you apply an annotation, you give values to its members.
// A simple annotation type.
@interface MyAnnotation {
String stringValue();
int intValue();
}
public class MainClass {
// Annotate a method.
@MyAnnotation(stringValue = "Annotation Example", intValue = 100)
public static void myMethod() {
}
}
