Scala Programming: Create a list in different ways

Last update on June 12 2025 12:57:31 (UTC/GMT +8 hours)

Write a Scala program to create a list in different ways.

Note: Use Lisp style, Java style, Range list, Uniform list, Tabulate list.

Sample Solution:

Scala Code-1:

object Scala_List
{
  def main(args: Array[String]): Unit = 
 {
   println("Create a Scala List:")
   println("Lisp style:")
   val lisp_list = 100 :: 200 :: 300 :: Nil :: 400 :: Nil
   println(lisp_list)
   println("Java style:")
   val nums = List(1,2,3,4,5,6,7)
   println(nums)
   println("Mixed type values in a list:")
   val x = List[Number](100, 200, 110.20, 45d, 0x1)
   println(x)
   println("Range List:")
   val y = List.range(1, 20)
   println(y)
   val z = List.range(0, 30, 3)
   println(z)   
   println("Uniform  List:")
   val s = List.fill(5)("Scala")
   println(s)
   val n = List.fill(3)(4)
   println(n)
   println("Tabulate List:")
   val t = List.tabulate(10)(n => n * n * n)
   println(t)
  }
}

Sample Output:

Create a Scala List:
Lisp style:
List(100, 200, 300, List(), 400)
Java style:
List(1, 2, 3, 4, 5, 6, 7)
Mixed type values in a list:
List(100, 200, 110.2, 45.0, 1)
Range List:
List(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
List(0, 3, 6, 9, 12, 15, 18, 21, 24, 27)
Uniform  List:
List(Scala, Scala, Scala, Scala, Scala)
List(4, 4, 4)
Tabulate List:
List(0, 1, 8, 27, 64, 125, 216, 343, 512, 729)
