Answer 1

//生成Workbook

HSSFWorkbook wb = new HSSFWorkbook();

//添加Worksheet（不添加sheet时生成的xls文件打开时会报错）

@SuppressWarnings("unused")

Sheet sheet1 = wb.createSheet();

@SuppressWarnings("unused")

Sheet sheet2 = wb.createSheet();

@SuppressWarnings("unused")

Sheet sheet3 = wb.createSheet("new sheet");

@SuppressWarnings("unused")

Sheet sheet4 = wb.createSheet("rensanning");

//保存为Excel文件

FileOutputStream out = null;

try {

out = new FileOutputStream("c:\text.xls");

wb.write(out);

} catch (IOException e) {

System.out.println(e.toString());

} finally {

try {

out.close();

} catch (IOException e) {

System.out.println(e.toString());

}

}
