Q. What will be the output of the following code –

import java.util.Iterator;
import java.util.Set;
import java.util.concurrent.CopyOnWriteArraySet;
public class CopyOnWriteArraySetTest
{
public static void main (String args[])
{
Set<String> copyOnWriteArraySet = new CopyOnWriteArraySet<String>();
copyOnWriteArraySet.add(” a “);
copyOnWriteArraySet.add ( ” b” );
Iterator<String> iterator = copyOnWriteArraySet.iterator();
while(iterator.hasNext())
{
copyOnWriteArraySet.add( ” c ” );
System.out.println(iterator.next());
}
}
}
