title: How to read from a file and save the content into a linked list?
body: <p>I'm trying to write the code for a program that saves the content of a txt file into a singly linked list, every line in the txt file represent an object. I used Scanner to read from the file but I don't know how to get the words in the list. </p>
  
  <p>any tip or hint is highly appreciated.</p>
  
  <p>my attempt: </p>
  
  <p>class Item </p>
  
  <pre><code>public class Item implements Serializable {
  private String name;
  private double price;
  
  public Item() {
  name="" ; 
  price=0.00 ;
  }
  
  public Item(String n, double p) {
  name = n ; 
  price = p ;
  }
  
  public void setName(String n) {
  name = n ;
  }
  
  public void setPrice(double p) { price = p ;
  }
  
  public String getName() { 
  return name ; 
  }
  
  public double getPrice() {
  return price ;
  }
  }
  </code></pre>
  
  <p>class Node </p>
  
  <pre><code>public class Node {
  public Item data ;
  public Node next ;
  
  public Node(Item d) {
      data = d ;
  }
  
  public Node(Item d, Node n) {
      data = d ; 
      next = n ; 
  }
  
  public String toString() {
      return data+"";
  }
  }
  </code></pre>
  
  <p>class ListItems</p>
  
  <pre><code>public class ListItems {
  
  private Node first;
  
  public ListItems(){
      first=null;
  }
  
  public boolean isEmpty(){
      return first==null;
  }
  
  public void addAnItems(Item d, int i){
      Node node1=new Node(d);
      node1.next=first;
      first=items.get(i);
  }
  
  public void displayList(){
      Node current = first;
  
          while(current != null){
          System.out.println(current.toString());
