The .set()
method replaces the current entry in the underlying collection of a ListIterator
object. This is the last item returned by the .next()
or .previous()
methods.
Syntax
myListIterator.set(value);
Where myListIterator
is a ListIterator
object, and value
is the object to use in replacing the current element in the underlying collection.
Example
This example populates an ArrayList
and then replaces the existing values in the collection:
import java.util.*;public class Example {public static void main(String args[]) {// Create a new ArrayListArrayList l = new ArrayList();// Add some items to the ArrayListl.add(1);l.add(2);l.add(3);l.add(4);l.add(5);System.out.println(l);ListIterator i = l.listIterator();// Loop through ArrayList contentswhile(i.hasNext()) {int item = (Integer) i.next();i.set(item * 2);}System.out.println(l);}}
This results in the following output:
[1, 2, 3, 4, 5][2, 4, 6, 8, 10]
