從文本文件刪除器導入數據

我有點困惑，試圖讓我的程序從文本文件中讀取。該文本文件由以下內容組成：客戶ID，客戶標題，客戶姓名，客戶姓名，客戶地址，客戶城鎮或客戶的郵政編碼，發行年份和保單號碼。其餘字段對應於策略編號所屬的策略類型。爲了將每個字段分開，我被告知DELIMITER。從文本文件刪除器導入數據

文本文件看起來像這樣：

IC-x00042W/Ms/LQ/Bethea/205, Willis Road/Bolton/BO5 1DQ/2007/C02000007/10000/0.5/2008/B27100037/150000/0.3/2011/V30200319/2000/21/1/0# 

IC-x00033D/Mr/R/Bowie/119, Thatcher Way/Glasgow/GL9 5SX/2008/L09000016/50000/45/2/2009/C74100008/8000/0.6/2012/B05300001/125000/0.5# 

IC-x00013A/MS/GRV/Blackwell/209, Drunk Road/Hawick/HK8 1MY/2013/B09000009/225000/0.1/2011/C14100014/20000/0.1/2010/V63200304/12000/43/5/1#

到目前爲止，我有東西，看起來像這樣：（有一類稱爲名稱包含了所有客戶的個人信息，幷包含所有一類叫做地址地址詳細信息）：

final String CLIENT_DELIMITER = "#"; 
    final String ITEM_DELIMITER = "/"; 

    Scanner fileScan = null; 
    Scanner clientScan = null; 

    /* 
    * ******************************************************************** 
    * 
    * Opening the text file and reading from the text file. If the 
    * File cannot be read then an error is thrown 
    * 
    * ******************************************************************** 
    */ 
    try { 
     fileScan = new Scanner(inputFile); 
    } catch (Exception e) { 
     System.out.println(e); 
    } 

    //******************************************************************** 

    String nxtClient = null; 


    //Define classes 
    ClientDetailsList clientInfo = null; 
    Name clientNameDetails = null; 
    Address clientFullAddress = null; 
    PolicyList clientPolicies = null; 
    ClientDetailsList clientDetails = null; 

    ClientDetailsList clientCollection = new ClientDetailsList(); 

    fileScan.useDelimiter(ITEM_DELIMITER); 

    /* 
    * ****************************************************************** 
    * Scan for client details from the text file 
    * ****************************************************************** 
    */ 

    while (fileScan.hasNext()) { 

     // Input the data for the next Client 
     nxtClient = fileScan.next().trim(); 
     clientScan = new Scanner(nxtClient); 
     clientScan.useDelimiter(ITEM_DELIMITER); 


     //Client Variables 
     String clientID = null; 
     clientScan.useDelimiter(ITEM_DELIMITER); 
     String clientTitle = null; 
     String clientInitials = null; 
     String clientSurname = null; 


     //Reads in details from name 
     clientID = fileScan.next().trim(); 
     clientTitle = fileScan.next().trim(); 
     clientInitials = fileScan.next().trim(); 
     clientSurname = fileScan.next().trim(); 

     //Construct Name 
     clientNameDetails = new Name(clientTitle, clientInitials, clientSurname); 

     String clientAddress = null; 
     String clientTownOrCity = null; 
     String clientPostCode = null; 
     String policyDetails = null; 

     //Reads in details from address 
     clientAddress = fileScan.next().trim(); 
     clientTownOrCity = fileScan.next().trim(); 
     clientPostCode = fileScan.next().trim(); 

     //Construct Address 
     clientFullAddress = new Address(clientAddress, clientTownOrCity, clientPostCode);

你有什麼問題？ – 2013-03-10 16:54:57

我的程序無法從文本文件中讀取。到達ITEM DELIMITER時發生錯誤。我不確定這是爲什麼？ – 2013-03-10 16:57:56

哪個錯誤。它有一個錯誤消息。閱讀。或者粘貼在這裏。 – 2013-03-10 16:58:42

nxtClient = fileScan.next(); 
final String[] srcData = nxtClient.split("/"); 

if (srcData.length != 8){// 8? am i right? 
    System.err.println("wrong data line " + nxtClient); 
} 

for (int i = 0; i < srcData.length; i++){ 
srcData[i] = srcData[i].trim(); 
} 

clientNameDetails = new Name(srcData[0], srcData[1], srcData[2]); 
.....

這個看起來更簡單，比你的解決方案
