Answer 1

To avoid the ConcurrentModificationException, you should write your code like this:

import java.util.*;

public class SomeClass {

    public static void main(String[] args) {
        List<String> s = new ArrayList<String>();

        for(String a : args)
            s.add(a);

        ListIterator<String> it = s.listIterator();    
        if(it.hasNext()) {  
            String item = it.next();   
        }  

        System.out.println(s);

    }
}

A java.util.ListIterator allows you to modify a list during iteration, but not between creating it and using it.
