Sorting arraylist in Android in alphabetical order

suppose we have array list of User

User class have following params

param : 

 uid

 name

 address 

suppose ArrayList<User> users  has many values and we want it to sory by name then use following code.

Collections.sort(users, new Comparator<User>() {

        @Override

        public int compare(User u1, User u2) {

            return u1.name.compareToIgnoreCase(u2.name);           

        }

    });

above code will sort users array by name.
