How Can I Format the Day of the Month with Ordinal Indicators in Java?

Formatting Day of Month with Ordinal Indicators

In Java, the SimpleDateFormat class provides a way to format dates and times. While the d format specifier displays the day of the month as a number, there is no built-in way to format the day with an ordinal indicator (e.g., 11th, 21st, 23rd).

Using Guava

The Google Guava library provides a utility class that can be used to generate the ordinal indicator for a given day of the month. The following code snippet demonstrates how to use Guava to format the day of the month with an ordinal indicator:

import static com.google.common.base.Preconditions.*;

public class DayOfMonthOrdinal {

    public static String getDayOfMonthSuffix(final int n) {
        checkNotNull(n);
        checkArgument(n >= 1 && n = 11 && n <p><strong>Note:</strong> The Guava Preconditions class is used to perform input validation.</p>
