Scala Programming: Add single element and multiple elements to a given listbuffer/list

Scala Programming List Exercise-2 with Solution

Write a Scala program to add single element and multiple elements to a given listbuffer/list.

Sample Solution:

Scala Code:

object Scala_List
{
  import scala.collection.mutable.ListBuffer
  def main(args: Array[String]): Unit = 
 {
  //As a List is immutable we use ListBuffer
  var colors = new ListBuffer[String]()
  println("Add Single element in the said list:")
  colors +="Red"
  colors +="Green"
  colors +="Black"
  println(colors)
  println("Add multiple elements in the said list:")
  colors ++= List("Orange", "Pink", "Black")
  println(colors) 
  println("Convert the ListBuffer to a List:")
  val colors_list = colors.toList
  println(colors_list)   
  }
}

Sample Output:

Add Single element in the said list:
ListBuffer(Red, Green, Black)
Add multiple elements in the said list:
ListBuffer(Red, Green, Black, Orange, Pink, Black)
Convert the ListBuffer to a List:
List(Red, Green, Black, Orange, Pink, Black)
