## CLI Commands
Place scripts in a folder. After writing, run:

# Java
The script must contain a Main public class with a `public static main()` method:
```java
public class Main {
public static Object main(String name, int count) {
java.util.Map<String, Object> result = new java.util.HashMap<>();
result.put("name", name);
result.put("count", count);
return result;
}
}
```
**Important:**
- Class must be named `Main`
