Java ListIterator Sample Code

Description:

Using ListIterator, we can iterate all elements of a list in either direction. You can access next element by calling next() method, and also you can access previous element by calling previous() method on the list.


Code:
package com.myjava.listiterator;

import java.util.ArrayList;
import java.util.List;
import java.util.ListIterator;

public class MyListIterator {
    public static void main(String a[]){
        List<Integer> li = new ArrayList<Integer>();
        ListIterator<Integer> litr = null;
        li.add(23);
        li.add(98);
        li.add(29);
        li.add(71);
        li.add(5);
        litr=li.listIterator();
        System.out.println("Elements in forward directiton");
        while(litr.hasNext()){
            System.out.println(litr.next());
        }
        System.out.println("Elements in backward directiton");
        while(litr.hasPrevious()){
            System.out.println(litr.previous());
        }
    }
}

Example Output

Elements in forward directiton
23
98
29
71
5
Elements in backward directiton
5
71
29
98
23
