Scala Map: Remove key-value pairs

Last update on December 21 2024 10:27:14 (UTC/GMT +8 hours)

Write a Scala program to create a map and remove a key-value pair from it.

Sample Solution:

Scala Code:

object RemoveKeyValuePairFromMapExample {
  def main(args: Array[String]): Unit = {
    // Create a map
    var color_map = Map("Red" -> 1, "Green" -> 2, "Blue" -> 3, "Orange" -> 4)

    // Print the original map
    println("Original map: " + color_map)

    // Remove a key-value pair from the map
    val keyToRemove = "Blue"
    val updatedMap = color_map.removed(keyToRemove)

    // Print the updated map
    println("Updated map: " + updatedMap)
  }
}

Sample Output:

Original map: Map(Red -> 1, Green -> 2, Blue -> 3, Orange -> 4)
Updated map: Map(Red -> 1, Green -> 2, Orange -> 4)
