我已经创建了这段代码,PoiReadExcelFile 类会将“poi-test.xls”文件读入 HSSFWorkbook 对象。然后将“POI 工作表”读入 HSSFWorksheet 对象,然后读取 A1、B1、C1 和 D1 单元格中的值并显示到标准输出。
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Date;
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 PoiReadExcelFile {
public static void main(String[] args) {
try {
FileInputStream fileInputStream = new FileInputStream("poi-
test.xls");
HSSFWorkbook workbook = new HSSFWorkbook(fileInputStream);
HSSFSheet worksheet = workbook.getSheet("POI Worksheet");
HSSFRow row1 = worksheet.getRow(0);
HSSFCell cellA1 = row1.getCell((short) 0);
String a1Val = cellA1.getStringCellValue();
HSSFCell cellB1 = row1.getCell((short) 1);
String b1Val = cellB1.getStringCellValue();
HSSFCell cellC1 = row1.getCell((short) 2);
boolean c1Val = cellC1.getBooleanCellValue();
HSSFCell cellD1 = row1.getCell((short) 3);
Date d1Val = cellD1.getDateCellValue();
System.out.println("A1: " + a1Val);
System.out.println("B1: " + b1Val);
System.out.println("C1: " + c1Val);
System.out.println("D1: " + d1Val);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
当我运行此代码时,我得到了这个: 用法:BiffDrawingToXml [options] inputWorkbook 选项:-exclude-workbook 排除工作簿级记录 -sheet-indexes 具有指定索引的输出表 -sheet-namek 具有指定名称的输出表
有什么问题?
