I'm not sue why this isn't working.

I am instantiating an object "list" from the Shopkeeper class. I'm trying to get the user to type in a specific item and then have a total that outputs the total of the items they purchased. (I'm learning Java on my own and believe I have the terminology correct.) Here is the code.


package dark.dominion;


import java.util.Scanner;
import java.lang.System;


public class Shopkeeper
{
public static void list(){

int rope = 1;
int bedroll = 3;
int rations = 2;
int total = 0;
String list = "";

System.out.println("Welcome to my shop. We have rope, a bedroll"
+ " and rations. Type the name of the items you want.");

Scanner keyboard = new Scanner(System.in);
list = keyboard.nextLine();

total = Integer.parseInt(list);

System.out.println("Your total is: " + total);


I am using netbeans and here are the error messages:

Exception in thread "main" java.lang.NumberFormatException: For input string: "bedroll"

Thanks for any and all help!

NumberFormatException: For input string: "bedroll"

The parseInt() method doesn't think the String: "bedroll" has a vaid NumberFormat.
You should enter numeric digits and not letters.
