stream流用代码对汉字怎么排序

对于汉字的排序，需要先将汉字转换为拼音，然后再进行比较。以下是一个示例的排序代码：

import java.io.*;
import java.util.*;

public class Main {
    public static void main(String[] args) {
        try {
            // 读取文件
            BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(new File("input.txt"))));
            // 临时存储字符串
            String line;
            List<String> list = new ArrayList<String>();
            // 逐行读取，并存储到List中
            while ((line = br.readLine()) != null) {
                list.add(line);
            }
            br.close();
            // 排序
            Collections.sort(list, new Comparator<String>() {
                @Override
                public int compare(String o1, String o2) {
                    // 将汉字转换为拼音再进行比较
                    return ChineseToPinyin.convert(o1).compareTo(ChineseToPinyin.convert(o2));
                }
            });
            // 写出文件
            BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File("output.txt"))));
            for (String s : list) {
                bw.write(s);
                bw.newLine();
            }
            bw.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

class ChineseToPinyin {
    private HanyuPinyinOutputFormat format;
    private String[] pinyin;

    public String getPinyin(String src) {
        char[] srcChar = src.toCharArray();
        String[] tmp;
        String t = "";
        try {
            for (int i = 0; i < srcChar.length; i++) {
                tmp = PinyinHelper.toHanyuPinyinStringArray(srcChar[i], format);
                if (tmp == null) {
                    t += srcChar[i];
                } else {
                    t += tmp[0];
                }
            }
        } catch (BadHanyuPinyinOutputFormatCombination e) {
            e.printStackTrace();
        }
        return t;
    }

    public static String convert(String input) {
        ChineseToPinyin pt = new ChineseToPinyin();
        pt.format = new HanyuPinyinOutputFormat();
        pt.format.setCaseType(HanyuPinyinCaseType.LOWERCASE);
        pt.format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
        pt.format.setVCharType(HanyuPinyinVCharType.WITH_V);
        return pt.getPinyin(input);
    }
}

输入的汉字会按照拼音的排序写入到 output.txt 中。
