两个List<ResultBean> result = new ArrayList<>();，后一个List<ResultBean>的最后一个字段的值放到第一个

Question

两个List<ResultBean> result = new ArrayList<>();，后一个List<ResultBean>的最后一个字段的值放到第一个后一个如：
第一个：
result =[
    {"a":"1","b":"22","c":"null"},
    {"a":"2","b":"22","c":"null"},
    {"a":"3","b":"22","c":"null"}
]
第二个：
result2 =[
    {"a":"1","b":"null","c":"3"},
    {"a":"2","b":"null","c":"2"},
    {"a":"3","b":"null","c":"1"}
]
最后合并成：
result3 =[
    {"a":"1","b":"22","c":"3"},
    {"a":"2","b":"22","c":"2"},
    {"a":"3","b":"22","c":"1"}
]

Answer 1

result1.get(i).setc(result2.get(i).get(c));

Answer 2

结尾是getc()，手机上打错了
