In this tutorial, we will learn about the Java Access Modifier, its types, and how to use them with the help of examples. In Java, access modifiers are used to set the accessibility (visibility) of classes, interfaces, variables, methods, constructors, d

Protected Access Modifier: We can access protected access modifier either within package and outside the package but through inheritance only. It means variables, methods and constructors which are declared as protected in a base class can be accessed only by the child classes in other package. T...
This helps with encapsulation and information hiding since it allows you to change the implementation of a class without affecting the consumers who use only the public API of the class. Protected Keyword Protected is a Java keyword. This keyword is an access modifier, used before a method or ...
Any method, property, or constructor with the private keyword is accessible from the same class only. This is the most restrictive access modifier, and is core to the concept of encapsulation. All data will be hidden from the outside world: package com.baeldung.accessmodifiers; public class Su...

Java will still compile your code, so what gives? No access modifier at all means that the method or variable defaults to package protected. This means that only the same class and any class in the same package has access. You get all of the same access as protected minus the ability fo...
package-private(often just called package) means that other members of the same package have access to the item. package-private is the default access modifier and does not have a keyword, because package is used to specify the package for a class or interface. To declare package access for...
