Hi this is my code for main class and doubly linked class and node class but when I run the program ,in the concole will show this"datastructureproject.DoublyLinkedList@19ee1ac" instead of the random numbers .please help me thanks!

main class:

    public class Main {

    public static int getRandomNumber(double min, double max) {
        Random random = new Random();
        return (int) (random.nextDouble() * (max - min) + min);

    }

    public static void main(String[] args) {
        int j;
        int i = 0;
        i = getRandomNumber(10, 10000);
        DoublyLinkedList listOne = new DoublyLinkedList();

        for (j = 0; j <= i / 2; j++) {
            listOne.add(getRandomNumber(10, 10000));


        }
        System.out.println(listOne);

    }
}

doubly linked list class:

public class DoublyLinkedList {

private Node head ;
private Node tail;
private long size = 0;

public DoublyLinkedList() {
    head= new Node(0, null, null);
    tail = new Node(0, head, null);
}



public void add(int i){

head.setValue(i);
Node newNode = new Node();
head.setNext(newNode);
newNode.setPrev(head);
newNode = head;

}
  }

and the node class is like the class that you have seen before (Node prev,Node next,int value)
