How to create a JSON Key Set from two JSON string-CodePudding

I have two json string coresponding to "sig" and "enc".

String a={ "kty": "someText", "e": "someText", "use": "sig", "kid": "someText", "alg": "someText", "n": "someText"}

String b= { "kty": "someText", "e": "someText", "use": "enc", "kid": "someText", "alg": "someText", "n": "someText" }

I need to combine them both like this:

{ "keys": [ { "kty": "someText", "e": "someText", "use": "sig", "kid": "someText", "alg": "someText", "n": "someText" }, { "kty": "someText", "e": "someText", "use": "enc", "kid": "someText", "alg": "someText", "n": "someText" } ] }

The resulting JSON is nothing but JWKS which includes both sig and enc public keys. I have replaced the actual values for these parameters.

Try the below code :

public void test(){
        String a="{ \"kty\": \"someText\", \"e\": \"someText\", \"use\": \"sig\", \"kid\": \"someText\", \"alg\": \"someText\", \"n\": \"someText\"}";
        String b= "{ \"kty\": \"someText\", \"e\": \"someText\", \"use\": \"enc\", \"kid\": \"someText\", \"alg\": \"someText\", \"n\": \"someText\" }";
        JSONObject jsonObject = new JSONObject(a);
        JSONObject jsonObject1 = new JSONObject(b);
        JSONArray objects1 = new JSONArray();
        objects1.put(jsonObject);
        objects1.put(jsonObject1);

        JSONObject jsonObject2 = new JSONObject();
        jsonObject2.put("keys",objects1);
        System.out.println(jsonObject2);
    }

Output:

{"keys":[{"kty":"someText","e":"someText","use":"sig","kid":"someText","alg":"someText","n":"someText"},{"kty":"someText","e":"someText","use":"enc","kid":"someText","alg":"someText","n":"someText"}]}

Library used : org.json

Please refer to the following logic implemented with org.json library.

public void generateJSONObject() {
    String a = "{ \"kty\": \"someText\", \"e\": \"someText\", \"use\": \"sig\", \"kid\": \"someText\", \"alg\": \"someText\", \"n\": \"someText\"}";
    String b = "{ \"kty\": \"someText\", \"e\": \"someText\", \"use\": \"enc\", \"kid\": \"someText\", \"alg\": \"someText\", \"n\": \"someText\" }";
    JSONObject jsonObject1 = new JSONObject(a);
    JSONObject jsonObject2 = new JSONObject(b);
    JSONObject jsonObject = new JSONObject();
    jsonObject.append("keys", jsonObject1);
    jsonObject.append("keys", jsonObject2);
    System.out.println(jsonObject);
  }
