Java LinkedList previous next

Question

is there anything similar to .Net\'s LinkedListNode<(Of <(T>)>)..::.Next and LinkedListNode<(Of <(T>)>)..::.Previous prop

Answer 1

Use the List interface's listIterator() method to get a ListIterator object. From there you can use the hasNext(), next(), hasPrevious(), and previous() methods to navigate the list. Here's a very simple example using ListIterator.

import java.util.LinkedList;
import java.util.List;
import java.util.ListIterator;

...

List myList = new LinkedList();

myList.add("A");
myList.add("B");
myList.add("C");

...

ListIterator it = myList.listIterator();

if (it.hasNext()) {
    String s1 = it.next();
    System.out.println(s1);
}

The example code should print "A".
