I have a arraylist which contains objects
Serviceprovider serv; while(result.next()) serv = new Serviceprovider(); arraylist.add(serv); }
In serv object i have different listing fields like name , email, postedate etc.
I have to sort this arraylist by postedate .
I do not want to write it in query because on later stage i divide this arraylist in two
How can i do it.
Please help for that
Thanks in advance .
