我一直在尝试使用 HSSF 库从 SKL 文件中读取，我想从中读取并写入品牌 nes .XLS 文件

这是我的代码：


import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;

public class WriteReadExcel {

    public static void main(String[] args) throws FileNotFoundException, IOException {
        
        WriteReadExcel objhssf = new WriteReadExcel();
        //objhssf.writeToExcel();
        objhssf.readFromExcel();
    }
    
     public void writeToExcel() throws FileNotFoundException, IOException {
        
        //create a work object
        HSSFWorkbook wb = new HSSFWorkbook();
        
        // create a work sheet
        HSSFSheet wSheet = wb.createSheet("FirstHSSF");
        
        //create a row 
        HSSFRow wRow = wSheet.createRow(0);
        
        //create a column
        
        HSSFCell wCell = wRow.createCell(0);
        
        //write sth to this cell
        
        wCell.setCellValue("Hello");
        
        // save the file
        
        wb.write(new FileOutputStream("SimpleHSSF.xls"));
        
        //close the workbook
        wb.close();
        
    } 
    
    public void readFromExcel() throws FileNotFoundException, IOException {
        
        // create an object of fileinputstream
        
        FileInputStream file = new FileInputStream("FILE.xls");
        
        // create workbook object
        HSSFWorkbook wb = new HSSFWorkbook(file);
        
        // refer to the worksheet
        HSSFSheet wSheet = wb.getSheet("FirstHSSF");
        
        // get the row 
        HSSFRow gRow = wSheet.getRow(0);
        
        // get the column
        HSSFCell gCell = gRow.getCell(0);
        
        // get the value 
        String strValue = gCell.getStringCellValue();
        
        // print the value
        System.out.println(strValue);
        
        //close 
        wb.close();
    }

}

我不断收到此错误：无效的标头签名；读取 0x3B4C5857503B4449，预期为 0xE11AB1A1E011CFD0 - 您的文件似乎不是有效的 OLE2 文档

它似乎无法读取文件..

你能帮忙吗？您会注意到该文件具有 .xls 作为扩展名，但它不是 xls 文件，它是 sylk 。
