I'm trying to reverse the order of strings in an array. I get the error: Index 3 out of bounds for length 1. This works for int if I use numbers but not for words. Could you help me out?

```
public class Main {

    public static void main(String[] args) {
    // write your code here

        String [][] arr = {{"My"}, {"name" }, {"is"}, {"John"}};

        String arr1 = arr[0][3];
        String arr2 = arr[0][2];
        String arr3 = arr[0][1];
        String arr4 = arr[0][0];
        String arrAll = arr1+arr2+arr3+arr4;
        System.out.println(arrAll);
    }
}

```
