How can I sort a list of country names alphabetically in Java?

Alphabetically Sorting a List of Country Names

In this common programming task, we seek to arrange a list of country names alphabetically. To achieve this, let's explore a simple yet efficient solution.

Solution:

Java provides a convenient method to sort lists alphabetically using the Collections.sort method. This method takes a list of comparable elements as input and arranges them in ascending order. Strings, which represent country names in this case, are inherently comparable in Java.

Implementation:

<code class="java">// Create a list of country names
List<String> listOfCountryNames = new ArrayList<>();
listOfCountryNames.add("United States");
listOfCountryNames.add("Brazil");
listOfCountryNames.add("China");
listOfCountryNames.add("India");

// Sort the list alphabetically
Collections.sort(listOfCountryNames);</code>

Result:

After executing the Collections.sort method, the listOfCountryNames will contain an alphabetically sorted list of country names:

[Brazil, China, India, United States]

This straightforward approach utilizes the built-in sorting functionality of the Java Collections framework, making it a reliable and concise solution for sorting lists alphabetically.
