How can I sort a List alphabetically?

To sort a List alphabetically in Java, you can use the Collections.sort method and pass in your List as an argument.

Here's an example of how you can use this method to sort a List of strings alphabetically:

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

public class ListUtils {
  public static void sortAlphabetically(List<String> list) {
    Collections.sort(list);
  }
}

This code defines a sortAlphabetically method that takes a List of strings as an argument and sorts it alphabetically using the Collections.sort method.

To use this method, you can simply call it and pass in your List as an argument:

List<String> list = ...; // initialize the list
ListUtils.sortAlphabetically(list);

This will sort the List alphabetically.

If you want to sort the List in reverse alphabetical order, you can use the Collections.reverseOrder comparator:

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

public class ListUtils {
  public static void sortAlphabetically(List<String> list) {
    Collections.sort(list, Collections.reverseOrder());
  }
}

This code defines a sortAlphabetically method that takes a List of strings as an argument and sorts it in reverse alphabetical order using the Collections.sort method and the Collections.reverseOrder comparator.

I hope this helps! Let me know if you have any questions.
