HSSF。如何連接字符串中的每一列？

-1

我的數據以一種格式存儲（向下看）：[ - ]表示一個空白單元格，右邊的可能只有10個空格後的列。事情是這樣的：HSSF。如何連接字符串中的每一列？

 [string0] [-] [string1] [string2] [string3] .. [string10] [-]

如何改變這種代碼：

獲得完全的字符串，每一行fullString = [ - ] [字符串1] [字符串2] [STRING3] .. [string10 ] [ - ]。 StringBuilder的？或者如何？

//Get first sheet from the workbook 
HSSFSheet sheet = workbook.getSheetAt(0); 

//Iterate through each rows from first sheet 
Iterator<Row> rowIterator = sheet.iterator(); 
while(rowIterator.hasNext()) { 
    Row row = rowIterator.next(); 

    //For each row, iterate through each columns 
    Iterator<Cell> cellIterator = row.cellIterator(); 
    while(cellIterator.hasNext()) { 

     Cell cell = cellIterator.next();  
     switch(cell.getCellType()) { 
      case Cell.CELL_TYPE_STRING: 
       System.out.print(cell.getStringCellValue() + "\t\t"); 
       list1.add(cell.getStringCellValue()); 
       break; 
     } 
    } 
    System.out.println(""); 
} 
file.close(); 
FileOutputStream out = 
     new FileOutputStream("C:\\Users\\student3\\"+sfilename+".xls"); 
workbook.write(out); 
out.close();

下面是應該工作的例子。

Maven依賴：

<dependency> 
    <groupId>org.apache.poi</groupId> 
    <artifactId>poi</artifactId> 
    <version>3.9</version> 
</dependency> 
<dependency> 
    <groupId>org.apache.poi</groupId> 
    <artifactId>poi-ooxml</artifactId> 
    <version>3.9</version> 
</dependency>

代碼：

import org.apache.poi.hssf.usermodel.HSSFDataFormatter; 
import org.apache.poi.openxml4j.exceptions.InvalidFormatException; 
import org.apache.poi.ss.usermodel.*; 

import java.io.File; 
import java.io.FileInputStream; 
import java.io.IOException; 
import java.io.InputStream; 
import java.util.Iterator; 

public class StackOverflowQuestion18095443 { 

    public static void main(String[] args) { 
     if(args.length != 1) { 
      System.out.println("Please specify the file name as a parameter"); 
      System.exit(-1); 
     } 
     String sfilename = args[0]; 
     File file = new File("C:\\Users\\student3\\" + sfilename + ".xls"); 
     read(file); 
    } 

    public static void read(File file) { 
     try (InputStream in = new FileInputStream(file)) { 
      HSSFDataFormatter formatter = new HSSFDataFormatter(); 
      Workbook workbook = WorkbookFactory.create(in); 
      Sheet sheet = workbook.getSheetAt(0); 
      Iterator<Row> rowIterator = sheet.iterator(); 
      while (rowIterator.hasNext()) { 
       Row row = rowIterator.next(); 
       StringBuilder rowText = new StringBuilder(); 
       Iterator<Cell> cellIterator = row.cellIterator(); 
       while (cellIterator.hasNext()) { 
        Cell cell = cellIterator.next(); 
        String cellAsStringValue = formatter.formatCellValue(cell); 
        rowText.append(cellAsStringValue).append(" "); 
       } 
       System.out.println(rowText.toString().trim()); 
      } 
     } catch (InvalidFormatException | IOException e) { 
      e.printStackTrace(); 
     } 
    } 
}
