.hasNext()

The .hasNext() method returns true if an Iterator or a ListIterator object has more elements. Returns false otherwise.

Syntax

Boolean value = iterator.hasNext();

Where iterator is an Iterator or ListIterator object.

Example

The following example uses an Iterator to traverse an ArrayList:

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);

    Iterator i = l.iterator();

    // Loop through ArrayList contents
    while(i.hasNext()) {
      Object item = i.next();
      System.out.print(item + ", ");
    }
  }
}

This example outputs the following:

1, 2, 3, 4, 5,
