Excel 函数语言 第一个功能实现 附带java实现

功能：

excel代码

IF(OR(ISNUMBER(FIND("证券";T3;1));ISNUMBER(FIND("银行";T3;1));ISNUMBER(FIND("租赁";T3;1));ISNUMBER(FIND("信托";T3;1));ISNUMBER(FIND("保险";T3;1)));1;0)

java读取xls代码

import java.io.File;

import java.io.FileInputStream;

import java.io.InputStream;

import jxl.Cell;

import jxl.CellType;

import jxl.Sheet;

import jxl.Workbook;

import jxl.write.Label;

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:/红楼人物.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:/红楼人物1.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);

//判断单元格的类型, 做出相应的转化

if (wc.getType() == CellType.LABEL)

{

Label l = (Label) wc;

l.setString("新姓名");

}

//写入Excel对象

wwb.write();

wwb.close();

} catch (Exception e) {

e.printStackTrace();

} finally {

readwb.close();

}

}

}
