A modifiers affect runtime behaviour of class or method
- Access modifiers: public, protected, and private
- Modifier requiring override: abstract
- Modifier restricting to one instance: static
- Modifier prohibiting value modification: final
- Modifier forcing strict floating point behaviour: strictfp
Not all modifiers are allowed on all classes, for example an interface cannot be final and an enum cannot be abstract.
java.lang.reflect.Modifier contains declarations for all possible modifiers.
