updatexls.java

这是我自己做的一个选课系统

package org.chooseClass.jExcelOpera;

import java.io.File;

import jxl.Workbook;
import jxl.write.Label;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;

public class UpdateXLS {

	public boolean updateXLS(){
		
		try  
		{  
		//Excel获得文件  
		Workbook wb=Workbook.getWorkbook(new File("测试1.xls"));  
		//打开一个文件的副本，并且指定数据写回到原文件  
		WritableWorkbook book=  
		Workbook.createWorkbook(new File("测试1.xls"),wb);  
		//添加一个工作表  
		WritableSheet sheet=book.createSheet("第二页",1);  
		sheet.addCell(new Label(0,0,"第二页的测试数据"));  
		book.write();  
		book.close();  
		}catch(Exception e)  
		{  
		System.out.println(e); 
		return false;
		}  
		return true;
		
	}
}
