java.lang.StackOverflowError while adding items to list

Trying to add items to a list and print them, it compiles, but I'm getting a run time error where theres a stack over flow error. this is what the error prints out:

Exception in thread "main" java.lang.StackOverflowError
at List.<init>(List.java:5)
at List.<init>(List.java:9)
at List.<init>(List.java:9) <----- this line is repeated quite a few times

This is my code with the methods to adding and print the list. 

public class List {

private AthleteNode front;

public List(){
front = null;
}

public List athletes = new List();

//add athlete to the end of the list 
public void add(Athlete a){

AthleteNode node = new AthleteNode (a);
AthleteNode current; //temp node to iterate over the list

if(front == null)
    front = node;//adds the first element

else{
    current = front;
    while (current.next !=null)
    current = current.next;
    current.next=node;
    }

}

In your class List, you have a List instance field that gets initialized at its declaration

public List athletes = new List();

This means that every List will have a List which has a List which has a List, ad nauseam, causing a StackOverflowError as they are being constructed.

I'm not sure what you meant to do with that field, since you aren't using it anywhere. Just remove it.
