Vector Indexing

Read a value from a vector by index.

VectorIndexing.scala

object Main {
  def main(args: Array[String]): Unit = {
    val index = 
    val colors = Vector("red", "green", "blue")
    val chosen = colors(index)

    println("index=" + index)
    println("chosen=" + chosen)
  }
}

object Main {
  def main(args: Array[String]): Unit = {
    val index = 
    val colors = Vector("red", "green", "blue")
    val chosen = colors(index)

    println("index=" + index)
    println("chosen=" + chosen)
  }
}

object Main {
  def main(args: Array[String]): Unit = {
    val index = 
    val colors = Vector("red", "green", "blue")
    val chosen = colors(index)

    println("index=" + index)
    println("chosen=" + chosen)
  }
}

vector-indexing A vector supports index reads. Index zero reads the first element.
