Array Iteration and Modification

Question

Consider the following code segment.

```java
public class DoubleArray {
    public static void main(String[] args) {
        int[] numbers = {1, 2, 3, 4, 5};
        /* missing code */
        System.out.println(java.util.Arrays.toString(numbers));
    }
}
```

Which of the following, if used to replace `/* missing code */`, will correctly double the value of each element in the `numbers` array?

Accepted Answer

for (int i = 0; i < numbers.length; i++) { numbers[i] *= 2; }

Answer

for (int i = 1; i <= numbers.length; i++) { numbers[i] *= 2; }

Answer

for (int number : numbers) { number *= 2; }

Answer

for (int i = 0; i < numbers.length - 1; i++) { numbers[i] *= 2; }
