How to pass two curly braces as json value (not a string) for a json object in java?

I currently have a graphQL endpoint that has a request body with two json objects, variables and query. The request body should look like below:

{
    "variables": {},
    "query": "{n  uploadQueueSummary {n    fileNamen    createdByn    salesIdn    completedRowsn    totalRowsn    uploadUUIDn    uploadTimen    statusn    hasErrorsn    uploadTypen    demandTypen    errorRowsn    deletedRowsn    failedRowsn  }n}"
}

When I use the below code, the variables object value is coming as a String instead, regardless if hard-coded or get from POJO:

GraphQLQuery queryAndVars = new GraphQLQuery() //POJO class
JSONObject requestBody = new JSONObject;
requestBody.put("query",queryAndVars.getQuery());
requestBody.put("variables", "{}");

The request body is as below after I run my code:

{
    "variables": "{}",
    "query": "{n  uploadQueueSummary {n    fileNamen    createdByn    salesIdn    completedRowsn    totalRowsn    uploadUUIDn    uploadTimen    statusn    hasErrorsn    uploadTypen    demandTypen    errorRowsn    deletedRowsn    failedRowsn  }n}"
}

How can I set the JSONObject key (variables) value without treating it as a String?

    You should try this

    GraphQLQuery queryAndVars = new GraphQLQuery() //POJO class
JSONObject requestBody = new JSONObject();
requestBody.put("query",queryAndVars.getQuery());
requestBody.put("variables", new JSONObject());

    in Json {} is the representation of an object.

    Rather than string {} , pass it as new JSONObject()

    Replace your line :

    requestBody.put("variables", "{}");

    with this :

    requestBody.put("variables", new JSONObject());

    I think instead of using "{}" string, you can simply replace it with new Object() or new JSONObject() as follows:

    requestBody.put("variables", new Object());

    OR

    requestBody.put("variables", new JSONObject());
