如何使用正则表达式在Java中检查单词是否遵循辅音-元音交替模式

(?i)^(?!.*?(?:[aeiou]{2}|[^aeiou]{2}))[a-z]+$

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class WordAlternationChecker {

    // 核心正则表达式
    private static final String ALTERNATING_PATTERN = "(?i)^(?!.*?(?:[aeiou]{2}|[^aeiou]{2}))[a-z]+$";
    private static final Pattern pattern = Pattern.compile(ALTERNATING_PATTERN);

    /**
     * 检查一个单词是否遵循辅音-元音交替模式。
     *
     * @param word 待检查的单词字符串
     * @return 如果单词遵循交替模式则返回 true，否则返回 false。

    public static boolean checkAlternatingPattern(String word) {

            return false;
        }
        Matcher matcher = pattern.matcher(word);
        return matcher.matches();
    }

    public static void main(String[] args) {

            "rhythm",     // X (rhy-thm - 连续辅音th) - 注意：此正则将y视为辅音

            System.out.printf("单词 '%-10s': %s%n", word, isAlternating ? "符合" : "不符合");

    }

(?i)^(?!.*?(?:[aeiou]{2}|[^aeiou]{2}))[a-z]{2,}$

(?i)^(?!.*?(?:[aeiou]{2}|[^aeiou]{2}))(?:[a-z]{2})+$
