List Data Structure In Scala

To create list in scala, use:

scala> val data = List("lady gaga","barack obama","larry page")

To access an element of list, use its index:
scala> println(data(2))
larry page

To iterate the whole elements, use:

scala> for( d <- data){

     | println(d)

     | }

or

scala> data.foreach(println);

lady gaga

barack obama

larry page

To know what the size, use:

scala> data.length

To get the first element, use:

scala> data.head

To get the last element, use:
scala> data.last

To reverse the elements order, use:
scala> data.reverse
