Question

java 遍历json数组

json数组:[
{"first_id":1,"first_name":"中学","second_id":1-1,"second_name":"一年级","third_id":1-1-1,"third_name":"一年级一班","people":10},
{"first_id":1,"first_name":"中学","second_id":1-1,"second_name":"一年级","third_id":1-1-2,"third_name":"一年级二班","people":11},
{"first_id":1,"first_name":"中学","second_id":1-2,"second_name":"二年级","third_id":1-2-1,"third_name":"二年级一班","people":20},
{"first_id":1,"first_name":"中学","second_id":1-2,"second_name":"二年级","third_id":"1-2-2","third_name":"二年级一班","people":21},
{"first_id":2,"first_name":"高中","second_id":2-1,"second_name":"一年级","third_id":2-1-1,"third_name":"一年级一班","people":31},]
对上面json数组遍历成下面的样子
[{
"id":1,
"name":"中学",
"children":[{
"id":1-1,
"name":"一年级",
"children":[{
"id":1-1-1,
"name":"一年级一班",
"people":10,
},{"id":1-1-2,"name":"一年级二班","people":11}]},{"id":1-2,"name":"二年级",
"children":[{
"id":1-2-1,
"name":"二年级一班",
"people":20
},{
"id":1-2-2,
"name":"二年级一班",
"people":21}]}]},{"id":2,
"name":"高中",
"children":[{
"id":2-1,
"name":"一年级",
"children":[{
"id":2-1-1,
"name":"一年级一班",
"people":31}]}]}]
求大神用java帮忙写下

Answer 1

你的这个问题确实需要点时间；

我个人的思路是用 HashMap 和 List 这两种数据结构；

如果你了解二叉数的话，在用我说的上面的两种数据结构；

是能解决问题的；

如果对回答满意，请点【采纳答案】，如果还有问题，请点【追问】

希望我的回答对您有所帮助，希望能采纳。

Answer 2

现写了一个，本地测试完全满足你的要求，现把源代码和用到的jar包传为附件。有什么不会用的再追问。
