Scala Programming: Delete element(s) from a given List
Scala Programming List Exercise-4 with Solution
Write a Scala program to delete element(s) from a given List.
Sample Solution:
Scala Code:
object Scala_List
{
def main(args: Array[String]): Unit =
{
val nums = List(1, 3, 5, 7, 9, 11, 14, 12)
println("Original list:")
println(nums)
//As scala List is immutable, so we can’t delete elements from it, but
//filter out element(s) as per requirement.
println("Filter out 3 from the above list:")
val nums1 = nums.filter(_ != 3)
println(nums1)
println("Filter out numbers which are greater than 10:")
val nums2 = nums.filter(_ > 10)
println(nums2)
}
}
Sample Output:
Original list: List(1, 3, 5, 7, 9, 11, 14, 12) Filter out 3 from the above list: List(1, 5, 7, 9, 11, 14, 12) Filter out numbers which are greater than 10: List(11, 14, 12)
