JAVA JsonArray到常规多维数组

Question

So I have a method.

public String getWidgetConfigAsString(List<DashboardColumn> dashboardList) {
        Gson gson = new Gson();
        JsonArray widgetConfigJson = gson.toJsonTree(dashboardList).getAsJsonArray();

        for (int i = 0; i < widgetConfigJson.getAsJsonArray().size(); i++) {
            System.out.println(widgetConfigJson.getAsJsonArray().get(i));
        }

        return widgetConfigAsString;
    }

And this method returns :

{"widgets":["notary_registry","notary_tasks"]}
{"widgets":["calendar"]}
{"widgets":[]}

This is a JSF dashboard layout, basicly first row is first column of a dashboard and so on.

What I want to achieve is, to get just regular multi-Array which would give me output like :

{["notary_registry","notary_tasks"]}
{["calendar"]}
{[]}

Looks ugly, but.. does the job, will find someting, that looks good enough to use.. :)

for (int i = 0; i < widgetConfigJson.size(); i++) {

            if (widgetConfigJson.get(i).toString().contains("widgets")) {
                int a = widgetConfigJson.get(i).toString().indexOf('[');
                int b = widgetConfigJson.get(i).toString().indexOf(']');

                System.out.println(widgetConfigJson.get(i).toString().substring(a, b + 1));
            }
