Scala Access Modifier

Access modifier is used to define accessibility of data and our code to the outside world. You can apply accessibly to classes, traits, data members, member methods and constructors etc. Scala provides least accessibility to access to all. You can apply any access modifier to your code according to your application requirement.

Scala provides only three types of access modifiers, which are given below:

  1. No modifier
  2. Protected
  3. Private

In scala, if you don't mention any access modifier, it is treated as no modifier.

Following table contains information about accessbilty of access modifiers.

Modifier Outside package Package Class Subclass Companion
No access modifier Yes Yes Yes Yes Yes
Protected No No Yes Yes Yes
Private No No Yes No Yes

Scala Example: Private Access Modifier

In scala, private access modifier is used to make data accessible only within class in which it is declared. It is most restricted and keeps your data in limited scope. Private data members does not inherit into subclasses.


error: variable a in class AccessExample cannot be accessed in AccessExample
        p.a = 12
one error found

Scala Example: Protected Access Modifier

Protected access modifier is accessible only within class, sub class and companion object. Data members declared as protected are inherited in subclass. Let's see an example.


a = 10 

Scala Example: No-Access-Modifier

In scala, when you don't mention any access modifier, it is treated as no-access-modifier. It is same as public in java. It is least restricted and can easily accessible from anywhere inside or outside the package.


a = 10
