In Scala like other languages java and C++, a method can get access to the private fields of all objects of its class.
For example:
use case 1:
scala> class prwa{
private var value = 5
def incr() {value +=4 }
def current = value
}
use case 2:
scala> class prwaedu{
private var value = 2
def incr() {value +=3 }
def current = value
}
use case 3:
scala> class A2{
private var value = -3
def incr() {value +=1 }
def current = value
}
