这个字典的错误输出[重复]

Question

我不断收到此代码的错误输出。当我搜索密钥时，它总是给我 txt 文件的最后一个值。 例如： 这是我的文本文件...

 Sam,123 Main Line,555-0469,123-45-6789,2423.07
 Carla,456 Off Line,555-0101,987-65-4321,1246.15
 Woody,789 Off Rocker,555-0000,010-20-3040,1169.23
 Diane,678 Fifth Ave,555-0690,958-47-3625,10.55
 Norm,987 Suds Blvd.,555-8374,456-78-9000,11.2
 Cliff,321 Duds Lane,555-7282,621-12-1234,12.0
 Tom,2631 Main Blv,423-1155,524-332-6654,10.0
 Kristen,443 Norfolk str,765-9457,010-332-1111,20.0

当我尝试搜索例如：# 621-12-1234

它应该给我 Cliff 的详细信息.. 但相反，它给了我 Kristen 信息。而且，它适用于我搜索的任何数字。

谢谢！

您只将一个对象放入地图中。

    StaffMember staff = new StaffMember();
    String line = null;
    while ((line = br.readLine()) != null)
    {

你需要很多对象

    String line = null;
    while ((line = br.readLine()) != null)
    {
        StaffMember staff = new StaffMember(); // Move into loop
