Hello,
Try something like this:
scala> def newFoo[T]()(implicit ct: ClassTag[T]): T =
ct.runtimeClass.newInstance().asInstanceOf[T]
newFoo: [T]()(implicit ct: scala.reflect.ClassTag[T])T
scala> newFoo[String]()
res2: String = ""
scala> newFoo[java.util.ArrayList[String]]()
res5: java.util.ArrayList[String] = []
