Compare two json which has same nested structure and same keys but values can be different?

Question

For example :

Json A =>
{
  "customer": {
    "age": 29,
    "fullName": "Emily Jenkins",
    "year":1988,
    "address":{
        "lineOne":"lineOne",
        "lineTwo":"lineTwo"
    }
},
  "handset":{
    "phone":"0123456789",
    "colour":"black"
  }
}

Json B =>
    {
      "customer": {
        "fullName": "Sammy J",
        "age": 31,
        "year":1985,
        "address":{
            "lineTwo":"lineTwo",
            "lineOne":"lineOne"
        }
    },
      "handset":{
        "colour":"red",
        "phone":"0123456788"
      }
    }

I want compare these two json and it should return true as keys are matching and both json structure is same. So is there a clean way of doing it?

I know using Gson lib I can compare two JsonElement but that would match values as well which I don't want to keep as constraint for my use-case.

JsonParser parser = new JsonParser();
JsonElement p1 = parser.parse(JsonA);
JsonElement p2 = parser.parse(JsonB);
System.out.printf(p1.equals(p2) ? "Equal" : "Not Equal"); //it returns true if values are same.
