How to remove an element from a collection while iterating over it

IteratorRemove.java

import java.util.Collection;
import java.util.Iterator;
import java.util.LinkedList;

public class IteratorRemove {
    static public void main(String[] args) {
        // Populate a collection
        Collection<Integer> ll = new LinkedList<>();
        for (int i = 0; i < 10; ++i) {
            ll.add(i);
        }

        // Remove some element
        Iterator<Integer> iter = ll.iterator();
        while (iter.hasNext()) {
            Integer val = iter.next();
            if (val.intValue() == 5) {
                iter.remove();
            }
        }

        // Print the collection
        for (Integer i : ll) {
            System.out.print(i.intValue() + " ");
        }
        System.out.println();
    }
}
