如何为每个scala版本创建不同的子类？

abstract class ParentClass {
  def printVersion(): Unit
}

class ChildClassScala2 extends ParentClass {
  override def printVersion(): Unit = {
    println("This is Scala 2.x")
  }
}

class ChildClassScala3 extends ParentClass {
  override def printVersion(): Unit = {
    println("This is Scala 3.x")
  }
}

object Main {
  def main(args: Array[String]): Unit = {
    val scalaVersion = "2.13.5" // 假设这是当前使用的Scala版本

    val childClass: ParentClass = scalaVersion match {
      case "2.x" => new ChildClassScala2()
      case "3.x" => new ChildClassScala3()
      case _ => throw new IllegalArgumentException("Unsupported Scala version")
    }

    childClass.printVersion()
  }
}
