GSON的基本用法三

import com.google.gson.Gson;


/**

public class GsonTester {

    public static void main(String args[]) {




        // 演示序列化
        Gson gson = new Gson();


        int[] ints = {1,9,5,8,7};
        System.out.println("案例1：" + gson.toJson(ints));


        String[] strings = {"123", "456", "789"};
        System.out.println("案例2：" + gson.toJson(strings));



        // 演示反序列化
        int[] ints2 = gson.fromJson("[1,2,3,4,5]", int[].class);

        String arr="";
        for (int i = 0; i <ints2.length ; i++) {

            arr+=ints2[i] + ",";

        }


        //这里的substring方法是截取最后一个逗号
        System.out.println("案例3：" + arr.substring(0,arr.length()-1));




    }

}
