使用jxl.jar，讓java可以處理excel表，下載jxl.jar的時(shí)候注意版本要和java虛擬機(jī)版本兼容
下面是類：
1
package excel;
2
3import java.io.File;
4
5import jxl.Cell;
6import jxl.Sheet;
7import jxl.Workbook;
8import jxl.write.Label;
9import jxl.write.WritableSheet;
10import jxl.write.WritableWorkbook;
11
12public class ExcelOperation

14
15 public static void main(String[] args) throws Exception
16
{
17 File file = new File("F:\\ceshi1.xls");
18 File file2 = new File("F:\\3883-3956.xls");
19 processExcel(file, file2, "年價(jià)明細(xì)");
20
}
