public class Part1_2 {

                public static void main(String[] args) {

                                ArrayList<String> names = new ArrayList<String>();

                                names.add("Wilson");

                                names.add("David");

                                names.add("John");

                                names.add("Eli");

                                names.add("Riley");

                                                System.out.println(name);

                                }

                                System.out.println("\n");

                                Collections.sort(names);                              

                                for (String name : names) {                         

                                                System.out.println(name);

                                }

                                System.out.println("\n");

                                Collections.shuffle(names);                        

                                for (String name : names) {                         

                                                System.out.println(name);

                                }

                                System.out.println("David: ["+Collections.binarySearch(names, "David")+"]");     

                                System.out.println("Eli: ["+Collections.binarySearch(names, "Eli")+"]");                  

                               

                                names.toArray();                                                            

                                System.out.println(names);
