Apache POI中讀取Excel的問題

Question

import org.apache.poi.hssf.usermodel.HSSFWorkbook; 
import org.apache.poi.hssf.usermodel.HSSFSheet; 
import org.apache.poi.hssf.usermodel.HSSFRow; 
import org.apache.poi.hssf.usermodel.HSSFCell; 
import java.io.FileInputStream; 
import java.lang.Iterable; 

public class ReadExcel { 
public static String fileToBeRead = "C:/Documents and Settings/Developer/Desktop/Anand exmps/Anand.xls"; 
public static void main(String argv[]) { 
try { 
    HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream(fileToBeRead)); 
    HSSFSheet sheet = workbook.getSheetAt(0); 
    //HSSFRow row = sheet.getRow(0); 
    //HSSFCell cell = row.getCell((short) 0); 
    for (Row row : sheet) { 
    for (Cell cell : row) { 
     System.out.println("THE TOP LEFT CELL–> "+ cell.getRichStringCellValue()); 
    } 
} 

} catch (Exception e) { 
    System.out.println("!! Bang !! xlRead() : " + e); 
} 

} 

} 

編譯上述程序時發生以下錯誤。究竟是什麼原因？請修復。我是java的初學者。

ReadExcel.java:16: cannot find symbol 
symbol : class Row 
location: class ReadExcel 
      for (Row row : sheet) { 
       ^
ReadExcel.java:17: cannot find symbol 
symbol : class Cell 
location: class ReadExcel 
      for (Cell cell : row) {

您忘記了導入和Cell類。

import org.apache.poi.ss.usermodel.Row; 
import org.apache.poi.ss.usermodel.Cell;

資源：

• HSSFSheet.getRow(int) returns a Row
• Row iterates on Cell
