如何使用java I/O将文本从一个文件传输到另一个文件

import java.io.*;

public class FileTransfer {
    public static void main(String[] args) {
        String inputFilePath = "input.txt";
        String outputFilePath = "output.txt";

        try {
            // 打开输入文件和输出文件
            FileInputStream inputFile = new FileInputStream(inputFilePath);
            FileOutputStream outputFile = new FileOutputStream(outputFilePath);

            // 创建输入流和输出流
            BufferedReader reader = new BufferedReader(new InputStreamReader(inputFile));
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputFile));

            String line;
            // 逐行读取输入文件
            while ((line = reader.readLine()) != null) {
                // 将文本写入输出文件
                writer.write(line);
                writer.newLine(); // 添加换行符
            }

            // 关闭输入流和输出流
            reader.close();
            writer.close();

            System.out.println("文本传输完成！");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
