stack overflow - java.lang.StackOverflowError while adding items to list -

-

trying add items list , print them, compiles, i'm getting run time error theres stack on flow error. error prints out:

exception in thread "main" java.lang.stackoverflowerror @ list.<init>(list.java:5) @ list.<init>(list.java:9) @ list.<init>(list.java:9) <----- line repeated quite few times

this code methods adding , print list. 

public class list {  private athletenode front;  public list(){ front = null; }  public list athletes = new list();  //add athlete end of list  public void add(athlete a){  athletenode node = new athletenode (a); athletenode current; //temp node iterate on list  if(front == null)     front = node;//adds first element  else{     current = front;     while (current.next !=null)     current = current.next;     current.next=node;     }  }

in class list, have list instance field gets initialized @ declaration

public list athletes = new list();

this means every list have list has list has list, ad nauseam, causing stackoverflowerror being constructed.

i'm not sure meant field, since aren't using anywhere. remove it.
