Hello,

What are the different types of access modifiers in JAVA?

[Praetor]

Java Access Modifiers (also known as Visibility Modifiers) regulate access to classes, fields and methods in Java. These modifiers determine whether a field or method in a class, can be used or invoked by another method in another class or sub-class. Access modifiers can be used to
restrict access, and therefore functionality, to certain classes and methods; often to enhance data integrity and prevent unauthorized alteration or execution of fields and methods of the particular object. Access modifiers are an integral part of object-oriented programming.

Thus, in summary, properties of Access modifiers:

- regulate access to classes, fields and methods

- can restrict access to certain classes and methods

- they are the integral part of object-oriented programming

In Java, access modifiers are declared with the class, method or field.

.. keywords that help set the visibility and accessibility of a class, its member variables, and methods.

If a class has public visibility, the class can be referenced by anywhere in the program. If a class has package visibility, the class can be referenced only in the package where the class is defined. If a class has private visibility, (it can happen only if the class is defined nested in an other class) the class can be accessed only in the outer class.

If a variable is defined in a public class and it has public visibility, the variable can be reference anywhere in the application through the class it is defined in. If a variable has package visibility, the variable can be referenced only in the same package through the class it is defined in. If a variable has private visibility, the variable can be accessed only in the class it is defined in.

If a method is defined in a public class and it has public visibility, the method can be called anywhere in the application through the class it is defined in. If a method has package visibility, the method can be called only in the same package through the class it is defined in. If a method has private visibility, the method can be called only in the class it is defined in.
