Java语言怎么进行多个文件的并行写入

public class ParallelFileWriter {
    private static final int THREAD_POOL_SIZE = 10;

    public void writeFiles(List<File> files) {
        ExecutorService executorService = Executors.newFixedThreadPool(THREAD_POOL_SIZE);

        try {
            // 分配每个文件的写入任务给不同的线程
            for (File file : files) {
                executorService.execute(new FileWriterTask(file));
            }
        } finally {
            executorService.shutdown();
        }

        try {
            // 等待所有线程执行完毕
            executorService.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);
        } catch (InterruptedException e) {
            e.printStackTrace();
            Thread.currentThread().interrupt();
        }
    }

    private static class FileWriterTask implements Runnable {
        private final File file;

        public FileWriterTask(File file) {
            this.file = file;
        }

        @Override

            try (OutputStream outputStream = new FileOutputStream(file)) {
                // 在这里写入文件的内容
                // 这里只是演示，可以根据实际需要进行修改
                for (int i = 0; i < 1000; i++) {
                    String content = "Line " + i + "\n";
                    outputStream.write(content.getBytes());
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    public static void main(String[] args) {
        // 准备待写入的文件列表
        List<File> files = new ArrayList<>();
        files.add(new File("file1.txt"));
        files.add(new File("file2.txt"));
        files.add(new File("file3.txt"));

        // 创建并行文件写入器实例
        ParallelFileWriter fileWriter = new ParallelFileWriter();

        // 执行文件写入操作
        fileWriter.writeFiles(files);
    }
}
