In this article, I recorded how MySQL is implemented to sort names alphabetically, and here's how this sort is implemented in Java. The code is as follows:1 PackageCom.review.chapter6;2 3 ImportJava.text.Collator;4 Importjava.util.Collections;5 ImportJava.util.Comparator;6 Importjava.util.Enumeration;7 ImportJava.util.Locale;8 ImportJava.util.Vector;9 Ten Importorg.junit.Test; One A /** - * This example demonstrates sorting by phonetic order in the
