👉 Rev is a Java class that represents a reverse iterator in Java. It's used to iterate over elements of an array or collection in reverse order, similar to how you might use the `reverse()` method for arrays or collections in other programming languages.
Here's a simple example of using Rev:
```java
import java.util.ArrayList;
import java.util.Arrays;
public class Main {
public static void main(String[] args) {
ArrayList
