java excel 输出 急！！！！！

Posted 2023-02-24

for(int i=0;i<GATE_List.size()-1;i++)
if(i% 2 == 0)

BigDecimal b1 = new BigDecimal(
(GATE_List.get(i).getFlightSpeed()+GATE_List.get(i+1).getFlightSpeed())/2);
double f1 = b1.setScale(2, BigDecimal.ROUND_HALF_UP).doubleValue();

BigDecimal b2 = new BigDecimal((GATE_List.get(i).getFlightHeight()+GATE_List.get(i+1).getFlightHeight())/2);
double f2 = b2.setScale(2, BigDecimal.ROUND_HALF_UP).doubleValue();

System.out.println(
// "GATE_List:"+
GATE_List.get(i).getFlight_ID()
+","+
GATE_List.get(i).getAC_Type()
+","+
f1
+","+
f2
);


以上我把数据装入在GATE_List里，它是ArrayList<GateDaten> GATE_List=new ArrayList<GateDaten>()， 里面分别是 flight ID，AC_Type，f1 是相对应一个flight ID 的飞机速度，f2 是高度。 我现在想输出到excel表格中
每一列的名称和上面名称相同 然后数据都自动在名称的下面。请高手指教！

public boolean createXLS(Admin admin,String subject,List products)
String url="d:/sawen/";
//String url = "f:/openreport/";

try
WritableWorkbook wwb = Workbook.createWorkbook(new File(url
+ admin.getAdminname() + ".xls"));
wwb.setProtected(true);
// 创建Excel工作表
WritableSheet ws = wwb.createSheet(subject, 0);
SheetSettings ss = ws.getSettings();
ss.setLeftMargin(0.2);

ss.setTopMargin(0.6);
ss.setBottomMargin(0.5);
ss.setHorizontalCentre(true);

我这是在项目中应用的，数据格式稍微不同，但是这个程序肯定是正确的，你可以参考。。。。 参考技术A jxl.jar 自己找资料
