如何在Java中读取/写入文件中的位？

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

public class FileReadWriteExample {
    public static void main(String[] args) {
        // 要读取的文件路径
        String inputFilePath = "input.txt";
        // 要写入的文件路径
        String outputFilePath = "output.txt";

        try (BufferedReader reader = new BufferedReader(new FileReader(inputFilePath));
             BufferedWriter writer = new BufferedWriter(new FileWriter(outputFilePath))) {

            String line;
            // 逐行读取文件
            while ((line = reader.readLine()) != null) {
                // 将读取到的每一行写入输出文件
                writer.write(line);
                writer.newLine();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
