Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1

This error occurs when you are trying to access an element in an array using an index that is out of range. In this specific case, the array has a length of 1 and you are trying to access an element at index 1, which does not exist.

For example, if you have an array of integers with only one element:

int[] numbers = {5};

If you try to access the second element in this array using index 1, you will get the ArrayIndexOutOfBoundsException:

System.out.println(numbers[1]); // Index 1 is out of bounds for length 1

To fix this error, make sure that your array index is within the bounds of the array length. In this case, you can only access the first element using index 0:

System.out.println(numbers[0]); // This will print 5
