Scala Programming: Remove single and multiple elements from a given listbuffer/list
Scala Programming List Exercise-3 with Solution
Write a Scala program to remove single and multiple elements from 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 and finally convert the ListBuffer to list.
var colors = new ListBuffer[String]()
colors +="Red"
colors +="Green"
colors +="Black"
colors +="Orange"
colors +="Pink"
println("Original ListBuffer:")
println(colors)
println("Remove one element:")
colors -="Red"
println(colors)
println("Remove multiple elements:")
println(colors)
colors --= Seq("Black", "Pink")
println("After removing two elements, final ListBuffer:")
println(colors)
println("Convert the ListBuffer to a List:")
val colors_list = colors.toList
println(colors_list)
}
}
Sample Output:
riginal ListBuffer: ListBuffer(Red, Green, Black, Orange, Pink) Remove one element: ListBuffer(Green, Black, Orange, Pink) Remove multiple elements: ListBuffer(Green, Black, Orange, Pink) After removing two elements, final ListBuffer: ListBuffer(Green, Orange) Convert the ListBuffer to a List: List(Green, Orange)
