使用jxl將excel-讀到java上

package excel;
import java.io.File;
import java.io.IOException;
import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
public class 
{
	
	public static void main(String[] args)
	{
		// TODO Auto-generated method stub
		try
		{
			//建立 workbook
			Workbook workbook = Workbook.getWorkbook(new File("C:/jxl_test.xls"));
			//得到第一個工作表
			Sheet sheet = workbook.getSheet(0);
			//取得資料
			for (int i = 0; i < sheet.getRows(); i++) //行
			{
				for (int j = 0; j < sheet.getColumns(); j++)//列
				{
					Cell cell= sheet.getCell(j,i);
					System.out.print(cell.getContents()+"  ");
				}
				System.out.println(); //換行
			}
      workbook.close(); //將workbook關閉
		} catch (Exception e)
		{
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}
