// 导入 countryNo string[] buf = File.ReadAllLines(textBox_CountryNo.Text); string[] buf2 = File.ReadAllLines(textBox_CityNo.Text); foreach (string line in buf) { string[] ss = line.Split('\t'); if (ss.Length < 2) continue; try { byte index = byte.Parse(ss[0], System.Globalization.NumberStyles.AllowHexSpecifier); if (!myCountryNoDict.ContainsKey(index)) { myCountryNoDict.Add(index, ss[1]); } } catch (Exception ee) { } } for (int ii = 0; ii < buf2.Length; ++ii) { myCityNoDict.Add(ii, buf2[ii]); } 转java

在Java中，你可以将上述代码转换为以下形式：

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.HashMap;
import java.util.Map;

public class CountryCity {
    public static void main(String[] args) {
        String countryNoFile = "path_to_countryNo_file.txt";
        String cityNoFile = "path_to_cityNo_file.txt";

        Map<Byte, String> myCountryNoDict = new HashMap<>();
        Map<Integer, String> myCityNoDict = new HashMap<>();

        try {
            String[] buf = Files.readAllLines(Paths.get(countryNoFile)).toArray(new String[0]);
            String[] buf2 = Files.readAllLines(Paths.get(cityNoFile)).toArray(new String[0]);

            for (String line : buf) {
                String[] ss = line.split("\t");

                if (ss.length < 2) continue;

                try {
                    byte index = Byte.parseByte(ss[0], 16);

                    if (!myCountryNoDict.containsKey(index)) {
                        myCountryNoDict.put(index, ss[1]);
                    }
                } catch (NumberFormatException ignored) {
                }
            }

            for (int ii = 0; ii < buf2.length; ++ii) {
                myCityNoDict.put(ii, buf2[ii]);
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

请确保将 `path_to_countryNo_file.txt` 和 `path_to_cityNo_file.txt` 替换为实际的文件路径。这段代码会读取两个文件，将数据存储在 `myCountryNoDict` 和 `myCityNoDict` 中。
