Subject: [Java] Java - Array List



Hi,
Please could someone help me with the following:

Modify the listNotes method so that it prints a number in front of each note that corresponds to its index in the ArrayList. For example:

0: Do some shopping
1: Wait for postman
2: Attend meeting at 10.45

This is the listNotes method which I have created so far:
/**
* List all notes in the notebook.
*/
public void listNotes()
{
for(String note : notes) {
System.out.println(note);
}
}
}

Thanks
