Java uses Apache Commons Codec to implement Soundex encoding and convert English words into a format similar to a phone number

Apache Commons Codec is a Java class library that provides various algorithm implementations for encoding and decoding, such as Base64, MD5, SHA, and Soundex. It can be used for encoding and decoding various binary and textual data. The Maven coordinates of the dependent class library are: <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.15</version> </dependency> Soundex is an algorithm used to convert English words into a format similar to a phone number. It is mainly encoded based on the pronunciation of words, and words with similar pronunciations will have the same encoding. The result of Soundex encoding is a string of length 4. The following is a complete example of using Apache Commons Codec to implement Soundex encoding: import org.apache.commons.codec.language.Soundex; public class SoundexExample { public static void main(String[] args) { String word = "hello"; Soundex soundex = new Soundex(); String soundexCode = soundex.encode(word); System.out.println("Word: " + word); System.out.println("Soundex Code: " + soundexCode); } } Output results: Word: hello Soundex Code: H400 In the above example, a Soundex object was first created. Then, the 'encode' method was used to encode the specified English words, resulting in the corresponding Soundex encoding. Finally, output the original words and encoding results to the console. Summary: By using the Soundex class of Apache Commons Codec, we can easily convert English words into a format similar to a phone number. Soundex encoding can be used to process words with similar pronunciation in text data for some text processing operations. Using Apache Commons Codec can simplify encoding and decoding operations.
