![**The following method is designed to count the number of odd numbers in an array.**
```java
public int countOdds(int[] array) {
return countOddsHelper(array, 0, array.length);
}
private int countOddsHelper(int[] array, int start, int stop) {
int count = 0;
if(start < stop) {
if(array[start] % 2 == 1) {
count++;
}
countOddsHelper(array, start+1, stop);
}
return count;
}
```
**Which of the following is true if the method is invoked with a non-empty array?**
- ☐ The code will run, but then will either crash or go into infinite recursion.
- ☐ None of these is correct.
- ☐ There is a compiler (syntax) error.
- ☐ The code will run, but there is a logical error.
- ☐ The code is correct.
**Explanation:**
The method `countOdds` is intended to count the number of odd integers in an array by invoking the helper method `countOddsHelper`. The method `countOddsHelper` uses recursion to iterate through the array, checking each element to see if it is odd and attempting to increment the `count` variable if the condition is met.
**Logical Flaw:**
- The `countOddsHelper` method lacks accumulation of the count from recursive calls. The `count` variable is reset to zero with each call, so it doesn't properly accumulate the number of odd numbers.
**Correct Answer:**
- The code will run, but there is a logical error.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7024c4db-e4c4-44c2-8fab-3045baf15ef1%2Fce4c9fee-2dc8-40b8-959a-b69c915b3f05%2Fxu022p_processed.png&w=3840&q=75)
