In Java, to get the last element in an array, we can access the element at the index array.length - 1 using array indexing. The length property of the array provides its total size, and subtracting one from it gives the index of the last element.

Example 1: Here, we will access the last element in an Integer array.

Java

// Get the last element  // in an integer array public class Geeks {     public static void main(String[] args) {                // Declare and initialize an array         int[] arr = {1, 2, 3, 4, 5};          // Access the last element         int l = arr[arr.length - 1];          // Print the last element         System.out.println("" + l);      } }

Output

Syntax

arrayName[arrayName.length - 1];

arrayName: The name of the array.
length: The total number of elements in the array.
- 1: Subtracting one gives the index of the last element.

Example 2: Here, we will access the last element in an array of Strings.

Java

// Access the last element  // in a String array public class Geeks {     public static void main(String[] args) {                // Declare and initialize a string array         String[] s = {"Cherry", "Strawberry", "Blueberry"};          // Access the last element         String l = s[s.length - 1];          // Print the last element         System.out.println("" + l);      } }

Output

Blueberry

Example 3: If we try to access the last element of an empty array, it will throw an ArrayIndexOutOfBoundsException.

Java

// Handling empty arrays public class Geeks {     public static void main(String[] args) {                // Declare an empty array         int[] arr = {};          // Check if the array is empty         if (arr.length > 0) {             System.out.println("" + arr[arr.length - 1]);         } else {             System.out.println("The array is empty.");         }     } }

Output

The array is empty.
