java - How to convert string array to object using GSON/ JSON? -
i have json this:
[ [ "passport number", "nationality", "reasons" ], [ "shais100", "india", "" ], [ "", "", "agent id not matched." ], [ "", "", "" ] ] i want populate arraylist<string[]>,please tell me how do?
and empty strings should not convert null.
that's simple, need following:
1.- first create gson object:
gson gson = new gson(); 2.- correspondent type list<string[]> (note can't list<string[]>.class due java's type erasure):
type type = new typetoken<list<string[]>>() {}.gettype(); 3.- parse json structure of type type:
list<string[]> yourlist = gson.fromjson(yourjsonstring, type);
