how to add array of string to jsonObject?

Question

In this method, I have an array of strings i.e barchartLabels. I want to add this array to jsonObject:

Expected output is :

{ "data" : " [ "January", "February", "March", "April", "May", "June", "July" ] " }

public String array() {
    JsonArray roleArray = new JsonArray();
    String barChartLabels[] = {"January", "February", "March", "April", "May", "June", "July"};
    Gson listG = new Gson();
    JsonObject jsonObj = new JsonObject();
    String list2 = listG.toJson(barChartLabels);
    jsonObj.addProperty("data", list2);
    roleArray.add(jsonObj);    
    return  jsonObj.toString(); 
}

In the above method I'm using Gson object to convert barchartLabels to string then using jsonObject adding it. But I'm getting the output as shown below. Is there any other way to do the above mentioned?

{ "data" : " [ \"January\", \"February\", \"March\", \"April\", \"May\", \"June\", \"July\" ] " }

It is the standard json format to escapse " so don't worry — Pavneet_Singh

This is not a problem, all that is happening is that your " " are being escaped. As @Pavneet_Singh has mentioned, this is completely standard. — Scott

data is a String, not a String[], so all the quotes are escaped. If you want a String[] just

    JsonArray data = new JsonArray();
    Stream.of(barChartLabels)
         .forEach(data::add);
    jsonObj.add("data", data);

listG.toJson is converting it to a JSON String, so when you add that, it's a String. Just skip that step and add it directly

method addproperty(string,string) in the jsonObject is not applicable for arguements(string,string[])

You could make this simpler by skipping the array and just starting with a Stream.of("foo", "bar", "etc...")

Sorry this is taking so long, I use POJOs and Jackson, so had to learn the Gson stuff
