Example
Utilize a ListIterator to traverse a list in both forward and backward directions.
|
import java.util.LinkedList;
import java.util.ListIterator;
public class Main {
public static void main(String[] args) {
// Make a collection
LinkedList<String> cars = new LinkedList<String>();
cars.add("Volvo");
cars.add("BMW");
cars.add("Ford");
cars.add("Mazda");
// Get the iterator
ListIterator<String> it = cars.listIterator();
// Loop through the list
while(it.hasNext()) {
System.out.println(it.next());
}
System.out.println("---");
// Loop backwards through the list
while(it.hasPrevious()) {
System.out.println(it.previous());
}
}

Definition and Usage
The listIterator() method provides a ListIterator for the list.
The ListIterator distinguishes itself from an Iterator by its ability to traverse the list in
reverse as well.
