将来自不同数组列表类的数据与不同实例合并

Question

我有两个不同的数组列表类，即不同的实例，即

//来自Claims.java arraylist类的数据

    List<Claim> list1 = new ArrayList<Claim>(claims.values());

打印出来

{
  "claims": [
    {
      "id": 98879,
      "Names": "Victor xxx"
    },
    {
      "id": 80790,
      "Names": "Mary xxx"
    }
   ]
}

//来自ServiceTag.java arraylist类的数据

List<ServiceTag> list2 = new ArrayList<ServiceTag>(servicetag.values());

打印出来

{
         "serviceTags": [
        {
          "quantity": 1,
          "claimid": 98879,
          "serviceType": pharmacy,
          "cost": 100
        },
        {
          "quantity": 1,
          "claimid": 80790,
          "serviceType": treatment,
          "cost": 400
        }
      ]
}

我想合并这两个列表并打印出基于声明的输出，即得到像

这样的东西

{
  "claims": [
    {
      "id": 98879,
      "Names": "Victor xxx",
      "serviceTags": 
        {
          "quantity": 1,
          "claimid": 98879,
          "serviceType": pharmacy,
          "cost": 100
        }
    },
    {
      "id": 80790,
      "Names": "Mary xxx",
      "serviceTags": 
        {
          "quantity": 1,
          "claimid": 80790,
          "serviceType": treatment,
          "cost": 400
        }
    }
   ]
}

Answer 1

听起来你想要ServiceTag（{1}}每个Claim的列表。因此，修改Claim并添加类似

的内容

private List<ServiceTag> serviceTags = new ArrayList<>();
public List<ServiceTag> getServiceTags() {
  return serviceTags;
}
public void addServiceTag(ServiceTag st) {
  serviceTags.add(st);
}
public void addServiceTags(Collection<ServiceTag> sts) {
  serviceTags.addAll(sts);
}
