import jxl.LabelCell;import jxl.Sheet;
import jxl.Workbook;
public class ExcelOperater
{
public static void main(String[] args)
{ jxl.Workbook readwb = null; try { //构建Workbook对象, 只读Workbook对象 //直接从本地文件创建Workbook InputStream instream = new FileInputStream("F:/tomcat7/webapps/Excel/upload/1.xls"); readwb = Workbook.getWorkbook(instream); //Sheet的下标是从0开始 //获取第一张Sheet表 Sheet readsheet = readwb.getSheet(0); //获得第一行第一列单元的值 Cell c00 = readsheet.getCell(1,1); //通用的获取cell值的方式,返回字符串 String strc00 = c00.getContents(); System.out.println("-----------------"); System.out.println(c00.getContents()); System.out.println("------------------"); //获得cell具体类型值的方式 if(c00.getType() == CellType.LABEL) { LabelCell labelc00 = (LabelCell)c00; strc00 = labelc00.getString(); } //获取Sheet表中所包含的总列数 int rsColumns = readsheet.getColumns(); //获取Sheet表中所包含的总行数 int rsRows = readsheet.getRows(); //获取指定单元格的对象引用 for (int i = 0; i < rsRows; i++) { for (int j = 0; j < rsColumns; j++) { Cell cell = readsheet.getCell(j, i); System.out.print(cell.getContents() + " "); } System.out.println(); } //利用已经创建的Excel工作薄,创建新的可写入的Excel工作薄 jxl.write.WritableWorkbook wwb = Workbook.createWorkbook(new File( "F:/tomcat7/webapps/Excel/upload/11.xls"), readwb); //读取第一张工作表 jxl.write.WritableSheet ws = wwb.getSheet(0); //获得第一个单元格对象 jxl.write.WritableCell wc = ws.getWritableCell(0, 0); //写入Excel对象 wwb.write(); wwb.close(); } catch (Exception e) { e.printStackTrace(); } finally { readwb.close(); }
}
}
