Для сортировки строк по алфавиту в Java можно использовать метод
sort() Arrays Collections String[] names = {"John", "Alice", "Bob", "Carl"};
Arrays.sort(names);
System.out.println(Arrays.toString(names)); // [Alice, Bob, Carl, John]
List<String> names = Arrays.asList("John", "Alice", "Bob", "Carl");
Collections.sort(names);
System.out.println(names); // [Alice, Bob, Carl, John]
reverse() Collections List<String> names = Arrays.asList("John", "Alice", "Bob", "Carl");
Collections.sort(names, Collections.reverseOrder());
System.out.println(names); // [John, Carl, Bob, Alice]
List<String> names = Arrays.asList("John", "Alice", "Bob", "Carl");
Collections.sort(names, (s1, s2) -> Integer.compare(s2.length(), s1.length()));
System.out.println(names); // [Alice, John, Carl, Bob]
sort()
