The implementation is for a linked list in java :

 public AnyType[] toArr() {

    AnyType[] arr = (AnyType[]) new Object[size];

    int i = 0;
    Node<AnyType> current = head.next;
    while (cur != head){

        arr[i] = current.data;// fill the array
        i++;
        current = current.next;

    }      

return arr;

}

public static void main(String[] args) {
System.out.println(ll.toArr().toString());

}

The error that I get:

Exception in thread "main" java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to [Ljava.lang.Integer;

Thanks.
