怎么把for循环里面获取到的数据，用一个方法封装起来，存放到itemSet里面

[jsaiihea]

public ActionForward saveItemContents(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws JSONException{
		JSONObject json = new JSONObject();
		json.put("result", true);
		try {
			Long contractorId = RequestUtils.getLongParameter(request, "contractorId", -1L);
			System.out.println("id===========>>>"+contractorId);
			String itemContents = RequestUtils.getStringParameter(request, "itemContents", "");
			JSONArray array  = new JSONArray(itemContents);
			Set<ContractorItem> itemSet = new HashSet<ContractorItem>();
			
			for (int i = 0; i < array.length(); i++) {
				
				JSONObject obj = array.getJSONObject(i);
				String id = obj.get("id").toString();
				String supplierNameFull = obj.get("supplierNameFull").toString();
				String companyProperty  = obj.get("companyProperty").toString();
				String procurementType = obj.get("procurementType").toString();
				String wareHousingReason  = obj.get("wareHousingReason").toString();
				
			}
		} catch (Exception e) {
			// TODO 自动生成的 catch 块
			e.printStackTrace();
			json.put("result", false);
		}
		return this.renderJson(response, json.toString());
		
	}
