What are Java modifiers?

Java provides two types of modifiers.

Access Modifiers 

  • The private access modifier is the most restrictive access level. Class and interfaces cannot be private. variables that are declared private can be accessed outside the class.
  • The public access modifier can be associated with class, method, constructor, interface, etc. public can be accessed from any other class. Therefore, fields, methods, blocks declared inside a public class can be accessed from any class.
  • The protected access modifier can be associated with variables, methods, and constructors, which are declared protected in a superclass can be accessed only by the subclasses in other package or any class within the package of the protected members' class.
  • The default access modifier does not have keyword A variable or method declared without any access control modifier is available to any other class in the same package.

Non Access Modifiers

  • The static modifier for creating class methods and variables.
  • The final modifier for finalizing the implementations of classes, methods, and variables.
  • The abstract modifier for creating abstract classes and methods.
  • The synchronized and volatile modifiers, which are used for threads.
