[英]I have a HashMap how can I integrate it with GUI; I want to type in the Integer & get the String value.
[英]How can I split the hashmap I have and get the information?
我有這樣的輸入 output。 這個output中的targetInfo最多可以進來三個元素,我想獲取里面的前三個元素。 所以我想將entertainment_interest_f、citizenship_s、tv_interest_f變量和值打印到屏幕上。 我該怎么做?
CollectiveInterestsRes(
targetInfo=[{entertainment_interest_f=3.0}, {citizenship_s->America=3.0}, {tv_interest_f=3.0}],
msisdnCount=3,
msisdnList=[495012072622, 495012103468, 495012115405],
isSuccess=true,
ruleRequests=[RuleRequest(ruleId=tv, subruleId=null, locationRequest=null, operator=EQ, values=[1], msisdnRequest=null)]
)
Class 內容如下:
public class CollectiveInterestsRes {
private List<Map<String,String>> targetInfo;
private Integer gsmNoCount;
private List<String> gsmNoList;
private boolean isSuccess;
private List<RuleRequest> ruleRequests;
}
我能夠將方法分解這么多,你能幫我更多嗎?
List<Map<String, String>> targetInfo = collectiveInterestsRes.get(0).getTargetInfo();
除了重構這個有點瘋狂的結構之外,您可以做的是遍歷列表並將所有元素放在一個公共的 map 中。然后按鍵訪問元素
final List<Map<String, String>> targetInfo = collectiveInterestsRes.get(0).getTargetInfo();
final Map<String, String> accumulatedMap = new HashMap<>();
targetInfo.forEach(accumulatedMap::putAll);
System.out.println(accumulatedMap.get("tv_interest_f"));
System.out.println(accumulatedMap.get("entertainment_interest_f"));
