I have JSON from file.
{
"from_excel":[
{
"solution":"Fisrt",
"num":"1"
},
{
"solution":"Second",
"num":"2"
},
{
"solution":"third",
"num":"3"
},
{
"solution":"fourth",
"num":"4"
},
{
"solution":"fifth",
"num":"5"
}
]
}
and want to parse list of Solution and Num.
Used lib org.json.simple.*
Try this one
Object obj = parser.parse(new FileReader("E:\json.txt")); JSONObject jsonObject = (JSONObject) obj; out.println(jsonObject.get("from_excel")); JSONObject obj_new = (JSONObject) jsonObject.get("from_excel"); JSONArray solution = (JSONArray) obj_new.get("solution"); Iterator iterator = solution.iterator(); while (iterator.hasNext()) { out.println(iterator.next()); }
What am I doing wrong?
If try to write
JSONObject solutions = (JSONArray) jsonObject.get("from_excel");
If try to write
JSONArray array = obj.getJSONArray("from_excel");See Question&Answers more detail:os
