What changes should i make in the below code so that it compiles & runs successfully :

Also i am looking forward to use only for-loop both normal and the enhanced for loop and not the while-loop to traverse through the list.

class x {
public static Iterator reverse(List list){
return list.iterator();
}

public static void main(String [] args){
List list = new ArrayList();
list.add("1");list.add("2");list.add("3");
for(Object obj:reverse(list))
System.out.print(obj + " " );
}
}

Hi,

public interface Iterable<T>

Implementing this interface allows an object to be the target of the "foreach" statement.


Check this implementation

Did you try to compile it?
If so, did it compile?
If not, what error message(s) did the compiler return?

If you did compile it, did you try to run it?
If so, did it work?
If not, what exceptions were thrown?


We're happy to help but first we like to see some effort on your part.
