Is there an equivalent of Java's this in Scala constructors?

Question

I have a Scala 2.11 constructor where I want one of the class' attributes to have the same name as one of the parameters in the constructor.

class Transition( next: Int ) {
    this.next = next // works in Java
}

This doesn't compile. I'm wondering what the equivalent of the assignment statement is in Scala.

Answer 1

Scala makes your life easy:

class Transition(val next: Int)

The val will make the constructor parameter into a field.
