P03 method subList

[tianhaolin1991]

I think you'd better use my codes below:

 public static <E> E findKthRecursive(LinkedList<E> list, Integer k){
        if(list.size()==0 || list==null){
            throw new NoSuchElementException("No elements in this list");
        }
        if(k >= list.size()){
            throw new IndexOutOfBoundsException("Index k is out of bounds");
        }
        if(k==0) return list.pollFirst();
        list.pollFirst();
        return findKthRecursive(list,k - 1);
    }

because the method sublist will create a SublistObject which has a field references the original list,if the original is very large,you will have a Memory leak,because the original list will never GC by JVM until your sublist without use.

PS:my English is very bad,so if anywhere offend/confuse you , or I say somthing wrong ,thanks for your feedback
