Java - Modifier

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
• Annotations

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.
