Thread: Can someone please tell me why my code doesn't print out anything?

Ok here's my main and printlinked method:

import java.util.Scanner;
 
public class ListTest
{
	public static void main(String []args)
	{
		Scanner keyboard = new Scanner(System.in);
		ListNode head = new ListNode();
		ListNode tail = head;
		head.link = null;
		System.out.print("Enter integers, seperated with blanks, to put into a linked list (type zero (0) to end): ");
		int in;
		in = keyboard.nextInt();
		while (in != 0)
		{
			ListNode x = new ListNode();
			x.link = null;
			x.data = in;
			tail = x;
		}
		printLinked(head.link);		
	}
 
	public static void printLinked(ListNode head)
	{
		System.out.println("The numbers in your linked list are:");
		while (head != null)
		{
			System.out.print(head.data + " ");
			head = head.link;
		}
	}
}

And here's the ListNode.java:

public class ListNode
{
	int data;
	ListNode link;
}
 
It builds fine but when I run it this part won't work:
 
	public static void printLinked(ListNode head)
	{
		System.out.println("The numbers in your linked list are:");
		while (head != null)
		{
			System.out.print(head.data + " ");
			head = head.link;
		}
	}

PLEASE help me

You forgot to link up every newly created node to the head.
