I want to edit a nested field of a Json using its path as a string. The path comes from a variable.

{
  "Type": "phone",
  "os": "android",
  "Transaction": {
    "Date": {
      Day: "22",
      Month: "Jan"
    },
    "value": "2000"
  }
}

I want to update say, Month value Jan to Dec

Can you please give a small code example to add a new field called Year to Date: json object with value say 2004 – Bishamon Ten May 19 '20 at 06:16
I don't have much knowledge of scala, In java, I would probably create a class corresponding to json and add the new field there and while converting json to java object, I would write the logic to populate the field. – Smile May 19 '20 at 07:26
I see. But that is not possible as I cannot have a fixed classes since my Json is changing. I need to change the Json string itself. Looking something like put of Jackson – Bishamon Ten May 19 '20 at 07:58
