import java.io.IOException; 
import jxl.Cell; 
import jxl.Sheet; 
import jxl.Workbook; 
import jxl.read.biff.BiffException; 
 
public class Test05 { 
public static void main(String args[]){ 
 File f=new File("table01.xls"); 
 try { 
  Workbook book=Workbook.getWorkbook(f);// 
  Sheet sheet=book.getSheet(0); //获得第一个工作表对象 
  for(int i=0;i<sheet.getRows();i++){ 
   for(int j=0;j<sheet.getColumns();j++){ 
    Cell cell=sheet.getCell(j, i); //获得单元格 
    System.out.print(cell.getContents()+" "); 
   } 
   System.out.print("\n"); 
  } 
 } catch (BiffException e) { 
  // TODO Auto-generated catch block 
  e.printStackTrace(); 
 } catch (IOException e) { 
  // TODO Auto-generated catch block 
  e.printStackTrace(); 
 } 
} 
}

Method 2:


package com.ij34.util;

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

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

*/
public class Test02 {
 public static void main(String[] args) throws FileNotFoundException, IOException {
  File excelFile = new File("table01.xls");
  HSSFWorkbook wb = new HSSFWorkbook(new FileInputStream(excelFile));
  HSSFSheet sheet = wb.getSheetAt(0);
  
  for (Row row : sheet) {
   for (Cell cell : row) {
    switch (cell.getCellType()) {
    case Cell.CELL_TYPE_STRING://字符串
     System.out.print(cell.getRichStringCellValue().getString());
     System.out.print(" ");
     break;
    case Cell.CELL_TYPE_NUMERIC://数值与日期
     if (DateUtil.isCellDateFormatted(cell)) {
      System.out.print(String.valueOf(cell.getDateCellValue()));
     } else {
      System.out.print(cell.getNumericCellValue());
     }
     System.out.print(" ");
     break;
    case Cell.CELL_TYPE_BOOLEAN://boolean类型
     System.out.print(cell.getBooleanCellValue());
     System.out.print(" ");
     break;
    default:
    }
   }
   System.out.println();
  }
}
}
