            Thread readerThread = new Thread(new Runnable() {
                public void run() {
                    try {
                        int data = read.read();
                        while (data != -1) {
                            System.out.print((char) data);
                            data = read.read();
                        }
                    } catch (Exception ex) {
                    }
                }
            });

            Thread writerThread = new Thread(new Runnable() {
                public void run() {
                    try {
                        write.write("I love my country\n".toCharArray());
                    } catch (Exception ex) {
                    }
                }
            });

            readerThread.start();
            writerThread.start();

        } catch (Exception ex) {
            System.out.println(ex.getMessage());
        }

    }
}

输出结果为：

I love my country
