使用Java命名约定

Question

So I have been building a soap message which takes elements and builds a soap structure. Don't be scared to take a stab at this if your unsure of this content. I'm looking for a changing variable name of some sort. All of the contents bellow are part of a line. Their can be several lines within a xml file so I have decided to loop it in an array, and insert them as an element individually. In the second chunk of code you can see "CHANGINGVARIABLE" however I do not know how to avoid this and keep inserting elements based on how many their are without predefining variables. Any tips or help would be greatly appreciated to make this work!

boolean finished = false; // true if there is no more item to process 

while(!finished) {
    String itemNumberz = eElement.getElementsByTagName("ItemNumber").item(cnt).getTextContent();
    String receiptTypez = eElement.getElementsByTagName("ReceiptType").item(cnt).getTextContent();
    String descriptionz = eElement.getElementsByTagName("ReceiptType").item(cnt).getTextContent();
    String locationCodez = eElement.getElementsByTagName("ReceiptType").item(cnt).getTextContent();
    String quantityz = eElement.getElementsByTagName("ReceiptType").item(cnt).getTextContent();
    String UnitOfMeasurez = eElement.getElementsByTagName("ReceiptType").item(cnt).getTextContent();
    String UnitCostz = eElement.getElementsByTagName("ReceiptType").item(cnt).getTextContent();

    listItemNumbers.add(itemNumberz);
    listReceiptTypes.add(receiptTypez);
    listDescriptions.add(descriptionz);
    listLocationCodes.add(locationCodez);
    listQuantitys.add(quantityz);
    listUnitOfMeasures.add(UnitOfMeasurez);
    listUnitCosts.add(UnitCostz);

    ++cnt;

    finished = (cnt >= eElement.getElementsByTagName("ItemNumber").getLength());
    //finished = (cnt >= eElement.getElementsByTagName("ReceiptType").getLength());
    System.out.println(cnt);
}

// use them :
int indexYouNeed = 1;
String itemNumber44 = listItemNumbers.get(indexYouNeed);
//System.out.println(itemNumber44);

Below is how I am applying them into the soap message.

while(cnt < 0) {
    String name = (cnt + "add");
    int[] CHANGINGVARIABLE = new int[cnt];
    CHANGINGVARIABLE[x] = someValue;


    SOAPElement CHANGINGVARIABLE = soapBodyElem7.addChildElement("LineItem");

    SOAPElement soapBodyElem9 = CHANGINGVARIABLE.addChildElement("ItemNumber");
    soapBodyElem9.addTextNode(listItemNumbers.get(cnt - 1));
    SOAPElement soapBodyElemaa = CHANGINGVARIABLE.addChildElement("ReceiptType");
    soapBodyElemaa.addTextNode(listReceiptTypes.get(cnt - 1));
    SOAPElement soapBodyElemaaa = CHANGINGVARIABLE.addChildElement("Description");
    soapBodyElemaaa.addTextNode(listDescriptions.get(cnt - 1));
    SOAPElement soapBodyElemaaaa = CHANGINGVARIABLE.addChildElement("Quantity");
    soapBodyElemaaaa.addTextNode(listQuantitys.get(cnt - 1));
    SOAPElement soapBodyElemaaaaa = CHANGINGVARIABLE.addChildElement("UnitOfMeasurement");
    soapBodyElemaaaaa.addTextNode(listUnitOfMeasures.get(cnt - 1));
    SOAPElement soapBodyElemaaaaaa = CHANGINGVARIABLE.addChildElement("UnitPrice");
    soapBodyElemaaaaaa.addTextNode(listUnitCosts.get(cnt - 1));
    SOAPElement soapBodyElemaaaaaaa = CHANGINGVARIABLE.addChildElement("LocationCode");
    soapBodyElemaaaaaaa.addTextNode(listLocationCodes.get(cnt - 1));

Answer 1

Given your explanation, you can either choose between using a list or an array. Then add new SOAPElements to the list or array by looping.

**For Array:**
SOAPElement[] soapArr = new SOAPElement[size];
for(int i=0; i < size; i++) {
    soapArr[i] = new SOAPElement();
}

**For List:**
List soapList = new LinkedList();
for(int i=0; i < size; i++){
    soapList.add(new SOAPElement());
}

Then loop through that second code chunk while referring to the CHANGINGVARIABLEs as the following:

soapArr[i] or soapList.get(i) .

I hope I'm understanding your need properly.
