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:
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.
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
