java - How to convert a number to its ordinal word in java

Question

EG:

• 1 -> first
• 2 -> second
• 3 -> third

and so on.

I looked at ICU4J, but it only has the option to convert to ordinal numbers, eg:

• 1 -> 1st
• 2 -> 2nd
• 3 -> 3rd

But this is not what I want.

我会用自定义枚举来做。您可以通过多种方式做到这一点，所以这只是一个粗略的例子来证明这一点。

import java.util.*;
import java.util.stream.*;

public class HelloWorld{

    enum PhrasedNumber {
       Zeroth, First, Second, Third, Fourth;
       static List<String> enumNames = Stream.of(PhrasedNumber.values())
                               .map(PhrasedNumber::name)
                               .collect(Collectors.toList());
    }
       

     public static void main(String []args){
        String phrase = PhrasedNumber.enumNames.get(2);
        System.out.println("Hello World " + phrase);
     }
}

输出如下所示：

Hello World Second
