So I’m trying to understand how to smear JSON on the object. What you see in the screenshot is, it is mapping Json with Java object (as I thought). Made by Mkyong.com/java/Jackson-2-Convert-JAVA-COs-To-From-JSON. It seemed to me if I would run Main method, it would pass the result of the response into the CITYLIST variable. CITYLIST object is simply Pojo object. I would understand what the mistake says.

I want a JSON answer via GET request (URL) pass to Java object

here:

import java.net.url;
Import com.fasterxml.jackson.databind.ObjectMapper;
Public Class Jacksonexample2 {
  Public Static Void Main (String [] Args) {
    OBJECTMAPPER MAPPER = NEW OBJECTMAPPER ();
    Try {
      URL URL = NEW URL ("https: // someurl");
      // JSON File To Java Object
      CityList CityList = Mapper.ReadValue (URL, CITYLIST.CLASS);
      // Compact Print.
      System.out.PrintLN (CityList);
    } Catch (IoException E) {
      E.PrintStackTrace ();
    }
  }
}

Simple Pojo object CityList:

package model;
  Import java.util.map;
  Public Class CityList {
  Private Map & Lt; String, String & GT; Plus_Code;
  Public Map & Lt; String, String & GT; getplus_code () {
    RETURN PLUS_CODE;
  }
  Public Void Setplus_Code (Map & Lt; String, String & GT; Plus_Code) {
    this.plus_code = plus_code;
  }
  }

Here is the answer JSON, example:

{
  "Plus_code": {
   "compound_code": "P27Q + MC New York, NY, USA",
   "Global_Code": "87G8P27Q + MC"
  }
}

introduced your JSON an example in the form of an object

Public Class CityList {
  @JsonProperty ("Plus_Code")
  Private Pluscode Pluscode;
  Public Pluscode getpluscode () {
    Return Pluscode;
  }
  Public Void Setpluscode (Pluscode Pluscode) {
    this.pluscode = pluscode;
  }
  Public Class Pluscode {
    @JsonProperty ("compound_code")
    Private String CompoundCode;
    @JsonProperty ("Global_Code")
    Private String Globalcode;
    Public String GetCompoundCode () {
      Return compoundcode;
    }
    Public Void SetCompoundCode (String CompoundCode) {
      this..compoundcode = compoundcode;
    }
    Public String GetGlobalcode () {
      RETURN GLOBALCODE;
    }
    Public Void Setglobalcode (String Globalcode) {
      this.globalcode = globalcode;
    }
  }
}

checked

Public Static Void Main (String [] Args) {
    OBJECTMAPPER MAPPER = NEW OBJECTMAPPER ();
    String Json = "{\" plus_code \ ": {\" compound_code \ ": \" P27Q + MC New York, NY, USA \ ", \" global_code \ ": \" 87G8P27Q + MC \ "}}";
    Try {
// URL URL = NEW URL ("");
      // JSON File To Java Object
      CITYLIST CITYLIST = MAPPER.REDVALUE (JSON, CITYLIST.CLASS);
      // Compact Print.
      System.out.PrintLN (cityList.getpluscode (). GetCompoundcode () + "" + cityList.getpluscode (). GetGlobalcode ());
    } Catch (IoException E) {
      E.PrintStackTrace ();
    }
  }

and got the desired result
