You should use GSON
or similar libs for this.
Store to DB
For example If you use GSON
Person p = new Person();
p.setname("xyz");
p.setage("18");
Gson gson = new Gson();
String personString = gson.toJson(p);
Now store this personString to DB.
Read from DB
Get back this object from database, read string from DB and convert it to object like below
String personStringFromDB = READ_LOGIC_OF_DB;
Gson gson = new Gson();
Person p = gson.fromJson(personStringFromDB, Person.class);
For more information, read GSON - Gson Example
