if  public int getLen(List al )
     {
	 if( al != null) return ( (String) al.get(0)).length();
	 else return 0;
     }

There could be a NPE if the given list has no elements.

Actually, it will throw an IndexOutOfBoundsException if the given list has no elements. It will throw NPE if al is null.

However, both are irrelevant to the question.
