創建3D數組對象

Question

我有3個獨立的對象，如GSMTable，SMSTable和GPRSTable。 這些包括2個字段srDate和numberOfSR。 現在我需要讓他們到一個三維數組對象，因爲我需要回到它爲我jqPlot線圖 這是我的要求：

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

我寫我自己的代碼像下面，但我不能完成它。

@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]] 

我需要合併gsmArray，smsArray和gprsArray作爲3D陣列 然後我期待陣列應該是：

[[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：

@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：
