CircleLinkList has a problem,i think

[picturetxl]

public void display()
{
Node current=head;
for (int i = 1; i <= size; i++) {
System.out.println(current.next.value);
current=current.next;
}
}

public static void main(String[] args)
{
    CircleLinkList<String> cl= new CircleLinkList<>();
    cl.append("hello");
    cl.append("world");
    cl.append("and");
    cl.append("java");

    cl.display();
    // System.out.println("hello java");
}

/**OutPut: Is it wrong? i have no idea

I agree that there's something wrong with this one. And I also found that the remove method doesn't work properly, it doesn't decrease the list size.

would you mind if I work on this one?
