How to Get First Element in Array in Java?

Last Updated : 24 Dec, 2024

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

 Cherry
