java linux fifo文件通信

1. mkfifo /tmp/fifo创建fifo文件。

2. java通信 

        

public class Read {

    public static void main(String[] args) throws FileNotFoundException, IOException {

        FileInputStream inputStream = new FileInputStream("/tmp/fifo");

        byte[] bs = new byte[1024];

        int n = 0;

        while ((n = inputStream.read(bs)) != -1) {

            System.out.println(n);

            System.out.println(new String(bs, 0, n));

        }

        System.out.println(n);

    }

}

public class Writer {

    public static void main(String[] args) throws FileNotFoundException, IOException, InterruptedException {

        FileOutputStream outputStream = new FileOutputStream("/tmp/fifo");

        for(;;){

        outputStream.write("abcdef".getBytes());

        outputStream.flush();

        Thread.sleep(1000);

        

        }

//        outputStream.close();

    }

}

这样可以实现java和c之间的通信，这里只有java的代码。以上代码只限制于linux平台。
