Overview

A sequence holds a collection of data objects and is a data storage structure in Clojure. The seq method is used to build a sequence.

In Clojure, the last sequence method returns the last element of a sequence. This can be used in cases where we need the last element from a sequence.

Syntax

(last seqq)
first sequence syntax

Parameters

seqq: This represents the sequence containing the element.

Return value

This method returns the last value of a sequence.

Example

(ns clojure.examples.example
(:gen-class))
(defn lastt []
(def seq1 (seq [1 2 8 9 1 0 6 8 2]))
(println (last seq1)))
(lastt)
last method in clojure sequence

Explanation

  • Line 3: We define a function lastt.
  • Line 4: We define our sequence seq1.
  • Line 5: We use the last method to get the last value of the seq1.
  • Line 6: We call the lastt function. Observe that the output returned "2" since it is the last element of the seq1 sequence.
