What are Access Specifiers in Java?

There are no access specifiers in java as like in c++. Now you can think that, public, private protected and default are what all these. These all called as access modifiers. Everywhere these four treated as access specifiers, but in java implementation these are considered as access modifiers. Now lets take a trip, wherether I am wrong or right. Simply write simple java program in eclipse or notepad and save in recomendade directroy. normal java program. public class accessModifiers { public static void main(String[] args) { System.out.println("Access Modifier Demo"); } } It will works normally... now change class definition from public to private, but private is not allowed. private class accessModifiers { public static void main(String[] args) { System.out.println("Access Modifier Demo"); } } then try to compile and execute program, you will get an error saying that. Error : Illegal modifier for the class accessModifiers; only public, abstract & final are permitted See this, java also treats these all as access modifiers. Access Modifier in java are. Java language has four access modifier to control access levels for classes, variable methods and constructor. Default : Default has scope only inside the same package Public : Public scope is visible everywhere Protected : Protected has scope within the package and all sub classes Private : Private has scope only within the classes. Non-access Modifier in java are : Non-access modifiers do not change the accessibility of variables and methods, but they do provide them special properties. Non-access modifiers are of 5 types, Final Static Transient Synchronized Volatile - See more at: https://www.urbanpro.com/java/what-are-access-specifiers-in-java#sthash.OfFW9n05.dpuf read less

Access Specifiers are for visibility of java objects . These are Public, Private, Protected and Default. Public: A variable or method that is public means that any class can access it. Private: These variables and methods are visible only in the classes , it defined including inner classes. Protected: Protected variables and methods allow the class itself to access them, classes inside of the same package to access them, and subclasses of that class to access them. Default: 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 for subclasses to access the method or variable (unless the subclass is in the same package). read less
