In Java, to get the first element in an array, we can access the element at index 0 using array indexing.

Example 1: Below is a simple example that demonstrates how to access the element at index 0 in an array.

Java

public class Geeks {     public static void main(String[] args) {                // Declare and initialize an array         int[] n = {5, 15, 25, 35, 45};          // Access the first element         int f = n[0];          // Print the first element         System.out.println("" + f);     } }

Output

Syntax

arrayName[0];

arrayName: The name of the array.
[0]: The index of the first element in the array.

Example 2: Here, we are trying to access the first element in 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[] n = {};          // Check if the array is empty         if (n.length > 0) {             System.out.println("The first element is: " + n[0]);         } else {             System.out.println("The array is empty.");         }     } }

Output

The array is empty.

Example 3: Here, we are accessing the first element in an Array of String.

Java

// Access the first 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 first element         String f = s[0];          // Print the first element         System.out.println(" " + f);     } }

Output
