Java JSON键的多个值

我是Java中JSON的初学者

如何创建这样的JSON对象

{
    "RECORD": {
        "customer_name": "ABC",
        "customer_type": "music"
    }
}

试着这样做：

    JSONObject jsonObject = new JSONObject();
    jsonObject.put("customer_name", "ABC");
    jsonObject.put("customer_type", "music");
    JSONObject jsonObject_rec = new JSONObject();
    jsonObject_rec.put("RECORD", jsonObject);
    System.out.println(jsonObject_rec);

您必须使“记录”成为JSONobject。这是一个例子：

JSONObject json = new JSONObject();

    // Add a JSON Object
    JSONObject Record = new JSONObject();
    Record.put( "customer_name", "ABC");
    Record.put( "customer_type", "music");
    json.put( "RECORD", Record);


    // P toString() 
    System.out.println( "JSON: " + json.toString() );
