Access Modifiers in scala are utilized to characterize the access field of members of packages, classes or objects in scala. For utilizing an access modifier, you should remember its keyword for the definition of package, class or object. These modifiers will restrict access to the members to the specific part of code.
Types of Access Modifiers
Private members
Protected members
Public members
Use case 1:
Private Members in Scala
class Prwatech {
private var a:Int=7
def show(){
a=6
println(a)
}
}
object access extends App{
var e=new Prwatech()
e.show()
}
output:
6
Use case 2:
Protected members in scala
class prwatech {
protected var a:Int=7
def show(){
a=8
println(a)
}
}
class prwatech1 extends prwatech{
def show1(){
a=9
println(a)
}
}
object access extends App{
var e=new prwatech()
e.show()
var e1=new prwatech1()
e1.show1()
//e.a=10
//println(e.a)
}
output:
8
9
Use case 3:
Public members in scala
class Example {
var a:Int=10
}
object access extends App{
var e=new Example()
e.a=5
println(e.a)
}
output:
5
