Transcribed Image Text:### Code Explanation:
The code provided is a Java program that defines a `Main` class with a `main` method and a private static method called `mystery`.
#### Main Method:
- An integer array `myArray` is initialized with the values `{3, 41, 7, 12, 9, 1, 15, 11, 17}`.
- A variable `result` is used to store the output of the `mystery` method, passing `myArray` as the argument.
- The `result` is printed to the console.
#### Mystery Method:
- This method takes an integer array `arr` as input.
- It initializes an integer `number` to 0.
- A `for` loop iterates over each element of the array.
- For each element, it checks if the element is greater than 8.
- If true, it adds the element's value to `number`.
- Finally, it returns the value of `number`.
### Output Calculation:
The `mystery` method sums all values in `myArray` that are greater than 8:
- Values greater than 8: `41, 12, 9, 15, 11, 17`
- Sum of these values: `41 + 12 + 9 + 15 + 11 + 17 = 105`
### Multiple Choice Options:
- 41
- 105
- 3, 7, 1, 15, 11, 17
- 83
### Correct Answer:
The correct output is `105`.
