HashMap.containsKey（）无法正常工作？

Question

因此，这个项目的基础是扫描一个包含名称的文件，然后在过去的一个世纪中每十年对其进行一次普及。我试图实现一个HashMap，但它似乎没有认识到名称就在那里（它是）。

import java.util.*; 

import java.io.*;
/**

 * Write a description of class NameRecord here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 * Implement a hashmap to seperate the name from the numbers to allow it to check.
 */

public class NameRecord
{

    ArrayList<Integer> namesList = new ArrayList<Integer>();
    HashMap<String, ArrayList> combined = new HashMap<String, ArrayList>();
    public void storeNames()
    {
        try
        {            
            Scanner scan = new Scanner(new File("names.txt"));
            while(scan.hasNextLine())
            {
                String firstName = scan.next();    
                while(scan.hasNext())
                {
                    int rank = scan.nextInt();
                    namesList.add(rank);
                }
                combined.put(firstName, namesList);
            }
        }
        catch(Exception e)
        {
        }           
    }

    public void nameRecord()
    {        
        System.out.println("What name would you like to search?");
        Scanner scan2 = new Scanner(System.in);
        String name = scan2.nextLine();
        System.out.println("\nThe name you chose to search was: " + name);
        if(combined.containsKey(name))
        {
            System.out.println("This name appears in the database");
        }
        else
        {
            System.out.println("This name does not appear in the database");
        }
    } 
}
