Answer 1

Try using Collections.sort(list); You may need to import java.util.Collections;

For using custom properties for sorting you will have to implement Comparator Example:

public class CustomComparator implements Comparator<Phonebook> {
   @Override
   public int compare(Phonebook p1, Phonebook p2) {
      return p1.name.compareTo(p2.name);
   }
}

And for sorting you will have to:

Collections.sort(list, new CustomComparator());
