java 数组去重复,该如何处理

java 数组去重复
{"deviceid":"460001204101325","distance":0.0,"maxspeed":0.0,"runningtime":"0秒"},{"deviceid":"460001204101325","distance":10.8,"maxspeed":42.0,"runningtime":"45分26秒"},
{"deviceid":"460001204101325","distance":15.0,"maxspeed":66.0,"runningtime":"26分30秒"},
{"deviceid":"460001204101325","distance":15.5,"maxspeed":55.0,"runningtime":"29分12秒"},
{"deviceid":"4609320402424","distance":35.2,"maxspeed":74.0,"runningtime":"1时42分27秒"},
{"deviceid":"4609320402424","distance":4.9,"maxspeed":25.0,"runningtime":"30分24秒"},
{"deviceid":"460706130100567","distance":0.0,"maxspeed":0.0,"runningtime":"0秒"},{"deviceid":"460706130100567","distance":88.6,"maxspeed":85.0,"runningtime":"1时22分3秒"},{"deviceid":"460706130100805","distance":26.4,"maxspeed":64.0,"runningtime":"50分59秒"}, 
把上面的数据只要deviceid是一样的都只取一个，后面的参数相加弄成下面这种的{"deviceid":"460001204101325","distance":41.3,"maxspeed":66.0,"runningtime":"1时31分08秒"},
{"deviceid":"4609320402424","distance":40.1,"maxspeed":74.0,"runningtime":"2时12分51秒"},
{"deviceid":"460706130100567","distance":88.6,"maxspeed":85.0,"runningtime":"1时22分3秒"},{"deviceid":"460706130100805","distance":26.4,"maxspeed":64.0,"runningtime":"50分59秒"},这个怎么弄？？？？

你这挺像Json的，可以先转成对象数组，再比较对象的属性进行过滤。

怎么弄？？？

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;


import com.google.gson.Gson;


public class JSonTest {


    public static void main(String[] args) {

        // 初始化JSON字符串数组// 这里的字符串，双引号是特殊字符，需要做转义处理

        String[] jsonStrArr = {

                "{\"deviceid\":\"460001204101325\",\"distance\":0.0,\"maxspeed\":0.0,\"runningtime\":\"0秒\"}",

                "{\"deviceid\":\"460001204101325\",\"distance\":10.8,\"maxspeed\":42.0,\"runningtime\":\"45分26秒\"}",

                "{\"deviceid\":\"460001204101325\",\"distance\":15.0,\"maxspeed\":66.0,\"runningtime\":\"26分30秒\"}",

                "{\"deviceid\":\"460001204101325\",\"distance\":15.5,\"maxspeed\":55.0,\"runningtime\":\"29分12秒\"}",

                "{\"deviceid\":\"4609320402424\",\"distance\":35.2,\"maxspeed\":74.0,\"runningtime\":\"1时42分27秒\"}",

                "{\"deviceid\":\"4609320402424\",\"distance\":4.9,\"maxspeed\":25.0,\"runningtime\":\"30分24秒\"}",

                "{\"deviceid\":\"460706130100567\",\"distance\":0.0,\"maxspeed\":0.0,\"runningtime\":\"0秒\"}",

                "{\"deviceid\":\"460706130100567\",\"distance\":88.6,\"maxspeed\":85.0,\"runningtime\":\"1时22分3秒\"}",

                "{\"deviceid\":\"460706130100805\",\"distance\":26.4,\"maxspeed\":64.0,\"runningtime\":\"50分59秒\"}" };


        List<RunInfo> runInfoList = getListByJsonStrArr(jsonStrArr);

        Gson gson = new Gson();

        System.out.println("最终结果：" + gson.toJson(runInfoList));


    }


    // 根据Json字符串数组，得到最终结果

    private static List<RunInfo> getListByJsonStrArr(String[] jsonStrArr) {

        if (null == jsonStrArr 
------解决方案--------------------
 0 == jsonStrArr.length) {

            return null;

        }


        // 使用谷歌Json转化器

        Gson gson = new Gson();


        // 使用Map来判断id是否重复

        Map<String, RunInfo> runInfoMap = new HashMap<String, RunInfo>();
