Scala Map: Find maximum value

Last update on December 21 2024 10:24:32 (UTC/GMT +8 hours)

Write a Scala program to create a map and find the maximum value in the map.

Sample Solution:

Scala Code:

object FindMaximumValueInMapExample {
  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)

    // Find the maximum value in the map
    val maxValue = color_map.values.max

    // Print the result
    println(s"The maximum value in the map is: $maxValue")
  }
}

Sample Output:

Original map: Map(Red -> 1, Green -> 2, Blue -> 3, Orange -> 4)
The maximum value in the map is: 4

Explanation:

In the above exercise,

• First, we create a map "color_map" using the Map constructor and provide key-value pairs.
• To find the maximum value in the map, we use the values method to obtain a collection of all the values in the map. Then, we use the max method on the collection to find the maximum value.
• Finally, we print the result using println, including the maximum value found.
