In this section of tutorial we will learn how to use the remove method of the Iterator interface. We will create an example to display the contents of the ArrayList.

  • remove()method removes the last element of the list.
  • This method is used with both Iterator and listIterator.
  • It is used with next() or previous() method.


Example Java Remove Iterator
import java.util.ArrayList;
import java.util.Iterator;
import java.util.ListIterator;

public class remove {

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