從Excel中讀取數據並使用Java POI從文本文件中檢索相關數據並在另一個excel中顯示結果

我想從Excel文件中讀取特定列數據並在具有附加數據的文本文件中搜索列的相關標題。我想用Java poi將這些細節打印回另一個excel文件。我的數據是這樣的：從Excel中讀取數據並使用Java POI從文本文件中檢索相關數據並在另一個excel中顯示結果

Excel中：

Name Number 
ABC 2345 
XYZ 6789

文本文件：

Name|Class|School 
ABC|1|bnm 
XYZ|2|hjk 
KOP|3|ert

我要在Excel輸出：

Name Class School 
ABC 1  bnm 
XYZ 2  hjk 





public static void main(String[] args) throws Exception { 
    String filename = System.getProperty("D:/Files/Input.xslx"); 
     List sheetData = new ArrayList(); 
     String columnWanted = "Name"; 
     Integer columnNo = null; 
     FileInputStream fis = null; 
     try { 
      fis = new FileInputStream(filename); 
      XSSFWorkbook workbook = new XSSFWorkbook(fis); 
      XSSFSheet sheet = workbook.getSheetAt(0); 
      Row firstRow = sheet.getRow(0); 
      for(Cell cell:firstRow){ 
       if (cell.getStringCellValue().equals(columnWanted)){ 
        columnNo = cell.getColumnIndex(); 
       } 
      } 
      if (columnNo != null){ 
      for (Row row : sheet) { 
       Cell c = row.getCell(columnNo); 
       if (c == null || c.getCellType() == Cell.CELL_TYPE_BLANK) { 
        // Nothing in the cell in this row, skip it 
       } else { 
        sheetData.add(c); 
           } 
       }System.out.println(sheetData); 
      }else{ 
       System.out.println("could not find column "); 
      } 
    // Taking a new array list 'arr' for printing result data 
      List arr =new ArrayList(); 
      File f=new File("D:/Files/Details.txt"); 
      Scanner in=new Scanner(f); 
      System.out.println("Read Data From The Txt file "); 
      while(in.hasNext()) 
      {  
    arr.add(in.nextLine()); 
         } 
      System.out.println(arr); 
      } 
     catch (IOException e) { 
      e.printStackTrace(); 
     } finally { 
      if (fis != null) { 
       fis.close(); 
      } 
     } 
    } 
     }
