Java .split() 不工作

Question

我正在尝试从文本文件中分割一行。文本文件是从库存系统导入的，我不知道如何将其格式化为表格格式。我无法告诉您文件中的内容，但我会解释我在说什么。保密...

第 1 行:

名称顺序顺序程序集 ID 描述日期

123 123 123 1-2-3 123-456-789 12-3 1\2\3

第 2 行:

123 123 123 1-2-3 123-456-789 12 3 1\2\3

如果您可以看到...描述列中有一个空格。这意味着它将把它分配到我的数组的单独部分中。第一个数组的大小为 7，但第二个数组的大小为 8。这是我所拥有的。

public static void main(String[] args) throws IOException, ParseException {

    ArrayList < CustordData > list = new ArrayList < CustordData > ();
    CustordData cd = new CustordData();
    int[] array = new int[10];
    DateFormat format = new SimpleDateFormat("MM/dd/Y");

    try {
      String read = null;
      BufferedReader in = new BufferedReader(new FileReader("Custord.txt"));
      while ((read = in .readLine()) != null) {
        String[] splited = read.split("\\s+");
        cd.setCustName(splited[0]);
        cd.setPurchaseOrder(splited[1]);
        cd.setSalesOrder(splited[2]);
        cd.setAssemblyID(splited[4]);
        cd.setOrderDesc(splited[5]);
        cd.setKitDate(format.parse(splited[6]));
      }
      for (CustordData d: list) {
        System.out.println(d.getCustName() + d.getPurchaseOrder() + d.getSalesOrder() + d.getAssemblyID() + d.getOrderDesc() + d.getKitDate() + d.getShipDate() + d.getPricePer() + d.getTotal());
      }

    } catch (IOException e) {
      System.out.println("There was a problem: " + e);
    }

如果您确定只有一列会有额外的空格，并且它将始终是同一列，您仍然可以使用 split，但您会做一些事情像这样:

Let N be the index of the description column, 
Assign columns [1, N-1] to the data you need
Assign columns [N, TotalColumns - 1] to description
Assign column TotalColumns to date

像这样:

   public static void main(String[] args) {
   String noSpaces = "123 123 123 1-2-3 123-456-789 12-3 1\\2\\3";
   String withSpaces = "123 123 123 1-2-3 123-456-789 12 3 1\\2\\3";

   String[] splitNoSpaces = noSpaces.split("\\s+");
   printData(splitNoSpaces);

   String[] splitWithSpaces = withSpaces.split("\\s+");
   printData(splitWithSpaces);

}

private static void printData(String[] data)
{
    int totalColumns = data.length;

    System.out.println("Name: " + data[0]);
    System.out.println("Order: " + data[1]);
    System.out.println("SOrder: " + data[2]);
    System.out.println("AssemblyID: " + data[3]);
    System.out.print("Description: ");
    for(int i = 4; i < totalColumns - 2; i++)
    {
        System.out.print(data[i] + " ");
    }
    System.out.println();
    System.out.println("AssemblyID: " + data[totalColumns - 1]);
}

产量:

Name: 123
Order: 123
SOrder: 123
AssemblyID: 1-2-3
Description: 123-456-789 
AssemblyID: 1\2\3
Name: 123
Order: 123
SOrder: 123
AssemblyID: 1-2-3
Description: 123-456-789 12 
AssemblyID: 1\2\3
