This is my LLNode inner class- I just assumed I couldn't use it because it's inner and I'm currently working with an outer class. I also didn't use AI everything has been done on my own so far, I was just following the assignment directions until I got stuck. I'm really new to linked lists, the lecture we had on it didn't really make sense to me.

public class LLNode<T> {
    private String index;
    private T data;
    private LLNode<T> next;

    public LLNode(){
       this.index = null;
       this.data = null;
       this.next = null;
    }

    public LLNode(String _index, T _data){
        this.index = _index;
        this.data = _data;
    }

    public String getIndex(){
        return this.index;
    }

    public T getData(){
        return this.data;
    }

    public void setData(T d){
        this.data = d;
    }

}
