Scala Programming: Merge (concatenate) given Lists
Scala Programming List Exercise-12 with Solution
Write a Scala program to merge (concatenate) given lists.
Sample Solution:
Scala Code:
object Scala_List
{
def main(args: Array[String]): Unit =
{
val nums1 = List(1,3,5,7,9)
val nums2 = List(2,4,6,8,10)
println("Original Lists:")
println(nums1)
println(nums2)
println("Merge the said two lists using the ++ method:")
val nums_1 = nums1 ++ nums2
println(nums_1)
println("Using ::: way:")
val nums_2 = nums1 ::: nums2
println(nums_2)
println("Using concat method:")
val nums_3 = List.concat(nums1, nums2)
println(nums_3)
}
}
Sample Output:
Original Lists: List(1, 3, 5, 7, 9) List(2, 4, 6, 8, 10) Merge the said two lists using the ++ method: List(1, 3, 5, 7, 9, 2, 4, 6, 8, 10) Using ::: way: List(1, 3, 5, 7, 9, 2, 4, 6, 8, 10) Using concat method: List(1, 3, 5, 7, 9, 2, 4, 6, 8, 10)
