在Java中循环使用JSON中的逻辑

Question

我有一个JSON数组。 JSON如下所述。每个JSON元素都有一个字段类型。我需要的是，如果当前字段类型是描述性的，我必须获取nexts数组元素，直到遇到下一个描述性字段类型。

{  
      "field_name":"form_name_1",
      "form_name":"patient_details",
      "section_header":"",

Answer 1

下面的代码将为您提供一个包含JSON数组的HashSet，其中包含每个部分的对象。

public void program()
{
    int sizeX = BuildingProperties.House.sizeX;
}

希望这就是你要找的东西
