如何使用Java POI生成Excel表文件 !

// 使用Java POI

// 把要两个JAR文件放到lib/ext下

// code run against the jakarta-poi-1.5.0-FINAL-20020506.jar.

// and commons-logging-1.0.jar

例子程序:

import org.apache.poi.hssf.usermodel.*;

import java.io.FileOutputStream;

// code run against the jakarta-poi-1.5.0-FINAL-20020506.jar.

// and commons-logging-1.0.jar

public class PoiTest {

static public void main(String[] args) throws Exception {

FileOutputStream fos = new FileOutputStream("d://foo.xls");

HSSFWorkbook wb = new HSSFWorkbook();

HSSFSheet s = wb.createSheet();

wb.setSheetName(0, "Matrix");

for(short i=0; i<50; i++) {

HSSFRow row = s.createRow(i);

for(short j=0; j<50; j++) {

HSSFCell cell = row.createCell(j);

cell.setCellValue(""+i+","+j);

}

}

wb.write(fos);

fos.close();

}

}
