java实现中文数字的排序

要实现中文数字的排序，可以使用Java的Comparator接口来自定义排序规则。以下是一个实现中文数字排序的示例代码：

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

public class ChineseNumberComparator implements Comparator<String> {
    private static final String CHINESE_NUMBER_PATTERN = "[零一二三四五六七八九十百千万亿]+";

    private static final String[] CHINESE_NUMBER_UNIT = new String[]{"亿", "万", "千", "百", "十"};

    private static final int[] CHINESE_NUMBER_UNIT_VALUE = new int[]{100000000, 10000, 1000, 100, 10};

    private static final String[] CHINESE_NUMBER_CHAR = new String[]{"零", "一", "二", "三", "四", "五", "六", "七", "八", "九"};

    private static int getChineseNumberValue(String s) {
        int value = 0;
        int lastUnit = 0;
        for (int i = 0; i < s.length(); i++) {
            char c = s.charAt(i);
            if (c == '零') {
                continue;
            }
            int digit = getChineseNumberCharValue(c);
            if (digit == 10) {
                if (lastUnit == 0) {
                    value += 10;
                } else {
                    value += lastUnit * 10;
                    lastUnit = 0;
                }
            } else if (digit > 0) {
                if (lastUnit == 0) {
                    value += digit;
                } else {
                    value += lastUnit * digit;
                    lastUnit = 0;
                }
            } else {
                int unit = getChineseNumberUnitValue(c);
                if (unit > lastUnit) {
                    lastUnit = unit;
                } else {
                    value += lastUnit;
                    lastUnit = unit;
                }
            }
        }
        if (lastUnit != 0) {
            value += lastUnit;
        }
        return value;
    }

    private static int getChineseNumberCharValue(char c) {
        for (int i = 0; i < CHINESE_NUMBER_CHAR.length; i++) {
            if (c == CHINESE_NUMBER_CHAR[i].charAt(0)) {
                return i;
            }
        }
        return -1;
    }

    private static int getChineseNumberUnitValue(char c) {
        for (int i = 0; i < CHINESE_NUMBER_UNIT.length; i++) {
            if (c == CHINESE_NUMBER_UNIT[i].charAt(0)) {
                return CHINESE_NUMBER_UNIT_VALUE[i];
            }
        }
        return 0;
    }

    @Override
    public int compare(String s1, String s2) {
        Matcher matcher1 = Pattern.compile(CHINESE_NUMBER_PATTERN).matcher(s1);
        Matcher matcher2 = Pattern.compile(CHINESE_NUMBER_PATTERN).matcher(s2);

        int result = 0;

        while (matcher1.find() && matcher2.find() && result == 0) {
            String str1 = matcher1.group();
            String str2 = matcher2.group();
            int value1 = getChineseNumberValue(str1);
            int value2 = getChineseNumberValue(str2);
            result = Integer.compare(value1, value2);
        }

        if (result == 0) {
            result = s1.compareTo(s2);
        }

        return result;
    }
}
