.hasPrevious()

The .hasPevious() method returns true if a ListIterator object has prior elements (i.e., elements before the current element). Returns false otherwise.

Syntax

Boolean value = iterator.hasPevious();

Where iterator is a ListIterator object.

Example

The following example uses a ListIterator to traverse an ArrayList and then traverse back:

import java.util.*;
public class Example {
public static void main(String args[]) {
// Create a new ArrayList
ArrayList l = new ArrayList();
// Add some items to the ArrayList
l.add(1);
l.add(2);
l.add(3);
l.add(4);
l.add(5);
ListIterator i = l.listIterator();
// Loop through ArrayList contents
while(i.hasNext()) {
Object item = i.next();
System.out.print(item + ", ");
}
System.out.println();
// Loop back through ArrayList contents
while(i.hasPrevious()) {
Object item = i.previous();
System.out.print(item + ", ");
}
}
}

This example outputs the following:

1, 2, 3, 4, 5,
5, 4, 3, 2, 1,
