创建一个新的 Json 文件，然后将其他 Json 文件附加到它

Question

需要创建一个新的 json 文件 (combined.json)，然后将多个 json 文件（json1 和 json2）附加到 combined.json.

示例：

Json 1 - 之前创建的 json 文件

[  
    {  
        "name":"John",
        "city":"Berlin",
        "cars":[  
            "audi",
            "bmw"
        ],
        "job":"Teacher"
    }
]

Json2 - 之前创建的 json 文件

[  
    {  
        "name":"Mark",
        "city":"Oslo",
        "cars":[  
            "VW",
            "Toyata"
        ],
        "job":"Doctor"
    }
]

最终产品：

Combined.json - 当前已创建 json 文件

[  
    {  
        "name":"John",
        "city":"Berlin",
        "cars":[  
            "audi",
            "bmw"
        ],
        "job":"Teacher"
    },
    {  
        "name":"Mark",
        "city":"Oslo",
        "cars":[  
            "VW",
            "Toyata"
        ],
        "job":"Doctor"
    }
]

Answer 1

    Gson gson = new com.google.gson.Gson();
    JSONArray combined = gson.fromJson(json1, JSONArray.class);
    combined.addAll(gson.fromJson(json2, JSONArray.class));
    // verify by looking on the value of: combined.toJSONString()
