how to check for an empty array java [duplicate]

Answer 1

As poited out in the other answers, the length property of Array will give the length of the array. But it is always recommended to check if the array is null before doing any operation on it or else it will throw NullPointerException if the array is null.

     if (array != null) {
            if (array.length == 0)
                System.out.println("Empty Array Size=0");
            else
                System.out.println("Array Not Empty -  Size = " + array.length);

        } else
            System.out.println("array is null");
    }
