Question

我一直在尝试编写一个简单的Java，用户可以在其中选择一个excel文件并让程序吐出文件的字符串/数字内容。

我已经达到了我认为可行的程序，但是当我尝试它时，我得到了一个大量的错误日志。该计划如下：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import javax.swing.JFileChooser;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.FormulaEvaluator;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;


public class WriteExcel {

    public static void main(String[] args) throws IOException {
        final JFileChooser fc = new JFileChooser();
        fc.setCurrentDirectory(new File(System.getProperty("user.home")));
        int result = fc.showOpenDialog(fc);
        File selectedFile = fc.getSelectedFile();

        String filename = selectedFile.getPath();
        System.out.println(filename);

        FileInputStream fis = new FileInputStream(filename);

        XSSFWorkbook wb = new XSSFWorkbook(fis);
        XSSFSheet sheet = wb.getSheetAt(0);

        FormulaEvaluator fe = wb.getCreationHelper().createFormulaEvaluator();

        for(Row row : sheet){
            for(Cell cell : row){
                switch(fe.evaluateInCell(cell).getCellType()){
                    case Cell.CELL_TYPE_NUMERIC:
                        System.out.print(cell.getNumericCellValue() + "\t\t");
                        break;
                    case Cell.CELL_TYPE_STRING:
                        System.out.print(cell.getStringCellValue() + "\t\t");
                        break;
                }
            }
        }
}
}

我收到的错误日志是：

肯定比我预期的错误消息多得多。任何人都可以指出我的错误（或分享如何更好地优化我的代码）？谢谢！
