[
  {
    "Version": 1,
    "Key": "353333_PC",
    "Type": "PostalCode",
    "Rank": 500,
    "LocalizedName": "Suwalki",
    "EnglishName": "Suwalki",
    "PrimaryPostalCode": "16-400",
    "Region": {
      "ID": "EUR",
      "LocalizedName": "Europe",
      "EnglishName": "Europe"
    },
    "Country": {
      "ID": "PL",
      "LocalizedName": "Poland",
      "EnglishName": "Poland"
    }
  }

  • The most simple way is using JSONNode. You can create the JSONNode from JSON string using com.fasterxml.jackson.databind.ObjectMapper. Then use findValue("key name") method to get the value from JOSNNode like jsonNode.findValue("key"). If it is a array iterate the JSONNode and get the value from the child node – Sangeetharaj Oct 05 '20 at 05:58
