The .remove() method removes an item from the underlying collection of an Iterator or a ListIterator object. This method removes the current element (i.e., the one returned by the last .next() or .previous() method).

Syntax

iterator.remove();

Where iterator is an Iterator or ListIterator object.

Example

This example populates an ArrayList and then removes the even items with the .remove() method:

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()) {
int item = (Integer) i.next();
// If item is even remove the element
if (item % 2 == 0) {
i.remove();
}
}
System.out.println(l);
}
}

This results in the following output:
