是否可以使用JAVA从文件读取/写入位？

import java.io.FileInputStream;
import java.io.IOException;

public class BitReader {
    public static void main(String[] args) {
        try {
            FileInputStream fileInputStream = new FileInputStream("input.txt");
            int bit = fileInputStream.read();
            while (bit != -1) {
                System.out.println(bit);
                bit = fileInputStream.read();
            }
            fileInputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

import java.io.FileOutputStream;
import java.io.IOException;

public class BitWriter {
    public static void main(String[] args) {
        try {
            FileOutputStream fileOutputStream = new FileOutputStream("output.txt");
            fileOutputStream.write(1); // 写入一个位
            fileOutputStream.write(0); // 写入另一个位
            fileOutputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
