創建3D陣列對象

Question

我有3個單獨的對象，例如GSMTable，SMSTable和GPRSTable。 這些包括2個稱為srDate和numberOfSR的字段。 現在，我需要將它們放到3D數組對象中，因為我需要將其返回給我的jqPlot折線圖，這是我的要求：

[
  [gsmTable.srDate][gsmTable.noOfSR],
  [smsTable.srDate][smsTable.noOfSR],
  [gprsTable.srDate][gprsTable.noOfSR]
]

我像下面那樣編寫了自己的代碼，但無法完成。

@RequestMapping(value = "/allGridView", method = RequestMethod.GET)
public @ResponseBody
Object[] showLineChart(Map<String, Object> map, HttpServletRequest request,
        HttpServletResponse response) {

    List<GSMTable> gsmList = contactService.fin();
    List<Date>gsmDateList=new ArrayList<Date>();
    List<Integer>gsmCount=new ArrayList<Integer>();
    Object[] gsmArray=new Object[2];
    for (Iterator iterator =gsmList.iterator();iterator.hasNext();) {
        GSMTable gsmTable=(GSMTable)iterator.next();
        gsmDateList.add(gsmTable.getSRDate());
        gsmCount.add(gsmTable.getNumberOfSR());
    }
    gsmArray[0]=gsmDateList.toArray(new Date[gsmDateList.size()]);
    gsmArray[1]=gsmCount.toArray(new Integer[gsmCount.size()]);     
    //=====================================================================================
    List<SMSTable> smsList = contactService.sms();
    List<Date>smsDateList=new ArrayList<Date>();
    List<Integer>smsCount=new ArrayList<Integer>();
    Object[] smsArray=new Object[2];
    for (Iterator iterator =smsList.iterator();iterator.hasNext();) {
        SMSTable smsTable=(SMSTable)iterator.next();
        smsDateList.add(smsTable.getSRDate());
        smsCount.add(smsTable.getNumberOfSR());
    }
    smsArray[0]=smsDateList.toArray(new Date[smsDateList.size()]);
    smsArray[1]=smsCount.toArray(new Integer[smsCount.size()]);
    //=====================================================================================
    List<GPRSTable> gprsList = contactService.gprs();
    List<Date>gprsDateList=new ArrayList<Date>();
    List<Integer>gprsCount=new ArrayList<Integer>();
    Object[] gprsArray=new Object[2];
    for (Iterator iterator =gprsList.iterator();iterator.hasNext();) {
        GPRSTable gprsTable=(GPRSTable)iterator.next();
        gprsDateList.add(gprsTable.getSRDate());
        gprsCount.add(gprsTable.getNumberOfSR());
    }
    gprsArray[0]=gprsDateList.toArray(new Date[gprsDateList.size()]);
    gprsArray[1]=gprsCount.toArray(new Integer[gprsCount.size()]);

    Object[][][] finalArray;
    //after that how to complete it ? ? ? 
    //need to return finalArray as 3D Object Array
    return finalArray;
}

gsmArray：

[[2012-11-05,05],[2012-11-06,08],[2012-11-07,10],[2012-11-08,14],[2012-11-08,09]]

smsArray：

[[2012-11-05,02],[2012-11-06,03],[2012-11-07,04],[2012-11-08,04],[2012-11-08,03]]

gprsArray：

[[2012-11-05,04],[2012-11-06,07],[2012-11-07,08],[2012-11-08,04],[2012-11-08,07]]

我需要將gsmArray，smsArray和gprsArray合並為3D數組，然后我的期望數組應該是：

[[2012-11-05,05],[2012-11-06,08],[2012-11-07,10],[2012-11-08,14],[2012-11-08,09],[2012-11-05,02],[2012-11-06,03],[2012-11-07,04],[2012-11-08,04],[2012-11-08,03],[2012-11-05,04],[2012-11-06,07],[2012-11-07,08],[2012-11-08,04],[2012-11-08,07]]

Answer 1

終於得到了解決方案：

    @RequestMapping(value = "/allGridView", method = RequestMethod.GET)
public @ResponseBody
Object[] showLineChart(Map<String, Object> map, HttpServletRequest request,
        HttpServletResponse response) {
    List<MapTable> gsmList = contactService.fin();
    Object[] gsmArray = new Object[gsmList.size()];
    int i = 0;
    for (Iterator iterator = gsmList.iterator(); iterator.hasNext();) {
        MapTable gsmTable = (MapTable) iterator.next();
        Object[] obj = new Object[2];
        obj[0] = gsmTable.getSRDate();
        obj[1] = gsmTable.getNumberOfSR();
        gsmArray[i] = obj;
        i++;
    }

    // =====================================================================================
    List<SMSTable> smsList = contactService.sms();
    Object[] smsArray = new Object[smsList.size()];
    i=0;
    for (Iterator iterator = smsList.iterator(); iterator.hasNext();) {
        SMSTable smsTable = (SMSTable) iterator.next();
        Object[] obj = new Object[2];
        obj[0] = smsTable.getSRDate();
        obj[1] = smsTable.getNumberOfSR();
        smsArray[i] = obj;
        i++;
    }
    // =====================================================================================
    List<GPRSTable> gprsList = contactService.gprs();
    Object[] gprsArray = new Object[gprsList.size()];
    i=0;
    for (Iterator iterator = gprsList.iterator(); iterator.hasNext();) {
        GPRSTable gprsTable = (GPRSTable) iterator.next();
        Object[] obj = new Object[2];
        obj[0] = gprsTable.getSRDate();
        obj[1] = gprsTable.getNumberOfSR();
        gprsArray[i] = obj;
        i++;
    }

    Object[] p=new Object[3];
    p[0]=gsmArray;
    p[1]=smsArray;
    p[2]=gprsArray;
    return p;
}

輸出：
