Here is the solution for the exercise. Notice how easy it is to sort elements with the Collections utility class!

import java.util.Collections;
import java.util.LinkedList;
import java.util.List;

public class SortingExample {

  public static void main(String[] args) {
    List<String> names = new LinkedList<String>();

    names.add("Mike");
    names.add("Bob");
    names.add("Alice");

    //Before  Sorting
    for (String name : names) {
      System.out.println(name);
    }

    //sorting
    Collections.sort(names);

    //after sorting
    for (String name : names) {
      System.out.println(name);
    }
  }
}
