In this section of tutorial we will learn how to use the previous method with the listIterator interface. We will create an example to display the contents of the ArrayList using previous method.

• Java previous Iterator function is present in the listIterator Interface.
• ListIterator is special iterator for the list.
• previuos method allows to get the one before element of the list.
• listIterator allows traversing in the both direction.

Java Previous Iterate Example

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

public class previous {

	public static void main(String[] args) {
		char alphabet = 'a';
		ArrayList list = new ArrayList();
		while (alphabet != 'z') {
			list.add(alphabet++);
		}
		
		ListIterator it = list.listIterator();
		while (it.hasNext()) {
			it.next();
		}
		while(it.hasPrevious())
		{
			System.out.print(it.previous()+"  ");
		}
	}
}
