用Java解码JSON格式 [英] Decoding JSON format in Java

问题描述

我得到了一个JSON(编码)格式的嵌套数组，看起来像这样；

I got a JSON(encoded) format nested Arrays which looks like this;

[
[[1234,245,10],[312,234,122],[1234,67788,345],[235,001,332]],
[[1234,245,10],[312,234,122],[1234,67788,345],[235,001,332],[1234,67788,3450]],
[[1234,245,10],[312,234,122],[1234,67788,345],[235,001,332],[1234,67788,34534]]]

因此，在上面的示例中，我有一个大数组，其中包含三个数组(有时可以是2个或三个以上数组)，并且这三个数组中的每个数组都包含一些数组.

So I have one big array which contains three arrays (this can be 2 or more than three arrays sometimes) and each of these three arrays contains some arrays, in this above example.

什么是反向过程(解码格式)?我的意思是，如果我想要这些数组中的值.

What is the reverse procedure (decoded format)? I mean what if I want those values from these arrays.

我尝试了org.json Java API，是这样吗?

I tried org.json Java API, is this right:

JSON JSONArray list = new JSONArray();
list.get()

推荐答案

    someArray[] array = [
    [[1234,245,10],[312,234,122],[1234,67788,345],[235,001,332]],
    [[1234,245,10],[312,234,122],[1234,67788,345],[235,001,332],[1234,67788,3450]],
    [[1234,245,10],[312,234,122],[1234,67788,345],[235,001,332],[1234,67788,34534]]]


    JSONArray superMasterArray = new JSONArray(array);
    if(superMasterArray != null){
        for(int i = 0; i < superMasterArray.length(); i++ ){
        JSONArray masterArray = (JSONArray) superMasterArray.get(i);
            for(int j = 0; j< masterArray.length(); j++){
                 JSONArray innerArray = (JSONArray) masterArray.get(j);
                 innerArray.getint(0);// gives 1st element of the inner array that is 1234
                 innerArray.getint(1);// gives 245
                 innerArray.getint(2);// gives 10
// if you dont know how many element in the given array, then loop it with size of array 
                }
            }
    }
