Java Enhanced For Loop Summation

Question

Consider the following `NumberAnalyzer` class definition.

```java
public class NumberAnalyzer {
  private int[] nums;

public int analyzeThis() {
    int sum = 0;
    for (int num : nums) {
      if (num % 2 == 0) {
        sum += num;
      }
    }
    return sum;
  }
  // Assume the constructor and other methods are defined elsewhere.
}
```

What is returned by a call to the `analyzeThis` method on a `NumberAnalyzer` object whose `nums` instance variable is initialized to `{2, 5, 8, 11}`?

Accepted Answer

The loop increments the `sum` by the array values that are divisible by 2: sum accumulates to 10.

Answer

The loop exits prematurely and returns a sum of 2 given an array index out of bounds at the first non-even number.

Answer

The loop includes all numbers, even and odd, making the sum 26.

Answer

The method returns a runtime error since the array includes values that are not integers.
