How to find largest key in Scala Map
In Scala, Map is same as dictionary which holds key:value pairs. In this article, we will learn how to find the largest key in given Map in Scala. The max() method is utilized to find the largest element of the map.
Syntax:
m1.max Here, m1 is name of a map.
Let’s try to understand it better with help of few examples.
Example #1:
// Scala program to get highest keys // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a map val m1 = Map(3 -> "Beginner", 4 -> "for", 2 -> "cs") // Displays max key println(m1.max) } } |
Output:
(4, for)
Example #2: Iterate over only keys using keysIterator
// Scala program to get highest keys // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a map val mapIm = Map("Ajay" -> 30, "Bhavesh" -> 20, "Charlie" -> 50) // Displays output println(mapIm.keysIterator.max) } } |
Output:
Charlie
