Question
Write a method reverse that takes an array as an argument and reverses it. Do not create a new array. Modify the array parameter.
Only edit code in the /* Your code goes here */ portions.
![The image displays a Java file open in an Integrated Development Environment (IDE), showing a class designed to reverse the order of elements in an array. Below is a transcription of the code snippet visible on the screen:
```java
public class ArrayUtils {
/**
* Reverses the order of the elements in an array.
*
* @param words an array of String to reverse.
*/
public static /* Your code goes here */ reverse(String[] words) {
for (int i = 0; i < words.length; i++) {
/* Your code goes here */;
}
}
}
```
### Explanation
- **Code Structure**: The class `ArrayUtils` contains a method `reverse`, designed to reverse an array of strings.
- **Comments**: The method is documented with Javadoc comments, explaining its use and parameter.
- **Loop**: A `for` loop is initiated to traverse the array, but the actions within the loop are not completed, indicated by the placeholder comments `/* Your code goes here */`.
### Missing Details
- **Method Body**: The logic for reversing the array is not provided, suggesting a need for implementation within the loop.
- **Return Type and Modifier**: The return type and visibility modifier of the `reverse` method are placeholders, indicating these need specification based on the final method implementation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd6e87594-a0d7-48c0-af39-cad58e8108aa%2F92612136-2a32-4893-b7ed-ae25c59e10d4%2F3rc3s1a_processed.jpeg&w=3840&q=75)
