vals map method in Clojure

A vals method is used to get all the values in a map.

Syntax

(vals hmap)

Parameter

The vals method receives one parameter:

hmap: This is the map with hash key and value.

Return value

The vals method returns a list of values in the map.

Example

(ns clojure.examples.example
   (:gen-class))
(defn valss []
   (def example (hash-map "z" "98" "x" "90" "u" "53"))
   (println (vals example)))
(valss)

Explanation

In the code above:

  • In line 3, we define a function valss.
  • In line 4, we define a variable example using the keyword def and we assign our map to it.
  • In line 5, we get the values of the map using the vals method and we print them out using the println method.
  • In line 6, we call the valss function.
