Java 如何：使用FileOutputStream编写文件？

我正在做的是，我正在为BufferOutputStream读取的文件和每行数据都将保存在一个FileOutputStream中，我想指定输出数据

如果我理解正确，您希望从S3下载文件并使用BufferedOutputStream写入本地目录

    S3Object object = s3.getObject(new GetObjectRequest(bucketName, key));
    InputStream is = object.getObjectContent();



 // Creating file
        File file= new File(localFilePath);
        FileOutputStream fos = new FileOutputStream(file);
        BufferedOutputStream bos= new BufferedOutputStream(fos);

    int read = -1;

    while ((read = is.read()) != -1) {
        bos.write(read);
    }

    bos.flush();
    bos.close();
    is.close();
