以下是将给定的代码片段转换为Java的等效代码：

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

public class CountryNoImport {
    public static void main(String[] args) {
        String[] buf;
        String[] buf2;
        HashMap<Byte, String> myCountryNoDict = new HashMap<>();
        HashMap<Integer, String> myCityNoDict = new HashMap<>();

        try {
            Path countryNoPath = Paths.get(textBox_CountryNo.getText());
            Path cityNoPath = Paths.get(textBox_CityNo.getText());

            buf = Files.readAllLines(countryNoPath).toArray(new String[0]);
            buf2 = Files.readAllLines(cityNoPath).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 e) {
                    // Handle exception
                }
            }

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

        } catch (IOException e) {
            // Handle exception
        }
    }
}

请注意，上述代码中的`textBox_CountryNo.getText()`和`textBox_CityNo.getText()`需要替换为实际的文本框或输入字段的逻辑。另外，这段代码只是将数据从文件中读取到`myCountryNoDict`和`myCityNoDict`中，并没有进行其他处理。你可能需要根据实际需求进行进一步的操作。
