Updating names in a contact list

A contact management system stores names in a list. When a name needs to be updated (e.g., correcting typos), you can use ListIterator to modify entries while iterating.

All the necessary classes from java.util have been imported for you.

Instructions

100 XP
  • Create a ListIterator object for the contacts list.
  • In the condition of the while loop, check if more elements are available in the contacts list.
  • Retrieve next element.
  • If a name is Jon, set it to John instead.
