java生成excel和读取excel例子

关于使用java的操作excel的方法有很多种，我的/article/8234352.html价绍过，下面是使用jxl生成xls格式的excel简单的代码。

使用jxl生成excel文件首先必须将jxl.jar的包加到你的项目的路径下。

package com.silence.excel;

import java.io.File;

import jxl.Workbook;

import jxl.write.Label;

import jxl.write.WritableSheet;

import jxl.write.WritableWorkbook;

public class jxlExcel {

public static void main(String[] args) {

// 设置该表格的行标签

String[] title = { "id", "name", "age", "sex", "number" };

// 创建文件

File file = new File("e:\\temp.xls");

try {

if (!file.exists()) {

file.createNewFile();

}

// 创建工作普

WritableWorkbook workbook = Workbook.createWorkbook(file);

// 创建sheet

WritableSheet sheet = workbook.createSheet("sheet0", 0);

Label label = null;

// 设置一行列名

for (int i = 0; i < title.length; i++) {

label = new Label(i, 0, title[i]);

sheet.addCell(label);

}

// 循环向每一行中插入数据

for (int i = 0; i < 10; i++) {

label = new Label(0, i, "user" + i);

sheet.addCell(label);

label = new Label(1, i, "张三" + i);

sheet.addCell(label);

label = new Label(2, i, 21 +i+"");

sheet.addCell(label);

label = new Label(3, i, "a" + i);

sheet.addCell(label);

label = new Label(4, i, "silencewaking in the sun " + i);

sheet.addCell(label);

}

//结束

workbook.write();

workbook.close();

} catch (Exception e) {

e.printStackTrace();

}

}

}

java读取excel

package com.silence.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 jxlReadExcel {

public static void main(String[] args) {

try {

//创建workbook

Workbook workbook = Workbook.getWorkbook(new File("e:\\temp.xls"));

//获取工作表sheet

Sheet sheet = workbook.getSheet(0);

for (int i = 0; i < sheet.getRows(); i++) {

for (int j = 0; j < sheet.getColumns(); j++) {

Cell cell = sheet.getCell(j,i);

System.out.print(cell.getContents()+" ");

}

System.out.println();

}

//获取数据

workbook.close();

} catch (BiffException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

}
