Generic Box Value

Store one value in a class with a type parameter.

GenericBoxValue.scala

case class Box[A](value: A)

object Main {
  def main(args: Array[String]): Unit = {
    val points = 
    val box = Box[Int](points)
    val doubled = box.value * 2

    println("value=" + box.value)
    println("doubled=" + doubled)
  }
}

case class Box[A](value: A)

object Main {
  def main(args: Array[String]): Unit = {
    val points = 
    val box = Box[Int](points)
    val doubled = box.value * 2

    println("value=" + box.value)
    println("doubled=" + doubled)
  }
}

case class Box[A](value: A)

object Main {
  def main(args: Array[String]): Unit = {
    val points = 
    val box = Box[Int](points)
    val doubled = box.value * 2

    println("value=" + box.value)
    println("doubled=" + doubled)
  }
}

generic-class A class can take a type parameter too. `Box[A]` stores one value while keeping the value's type known to the compiler.
