How to check if an Array is Empty in Java ?

Answer

To check if an array is empty in Java, you can compare its length with 0.

✐ Examples

1 Check if Given Array with Elements is Empty

In this example,

We create an integer array named numbers with some elements.
We check if the length of the array is 0 and store the result in the variable isEmpty.
Finally, we print whether the array is empty or not.

Java Program

// Check if Given Array with Elements is Empty
public class Main {
    public static void main(String[] args) {
        int[] numbers = {1, 2, 3};
        boolean isEmpty = numbers.length == 0;
        System.out.println("Array is empty: " + isEmpty);
    }
}

Output

Array is empty: false

2 Check if Array with no Elements is Empty

In this example,

We create an integer array named emptyArray without any elements.
We check if the length of the array is 0 and store the result in the variable isEmpty.
Finally, we print whether the array is empty or not.

Java Program

// Check if Array with no Elements is Empty
public class Main {
    public static void main(String[] args) {
        int[] emptyArray = new int[0];
        boolean isEmpty = emptyArray.length == 0;
        System.out.println("Array is empty: " + isEmpty);
    }
}

Output

Array is empty: true
