What are private, public, default and protected access Java modifiers?

The access specifiers are used to define the access restriction on the class and members of a class.

The private access modifier is the most restrictive access level. Class and interfaces cannot be private. Members 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.
