public class ProducerConsumer extends JFrame {
    private JTextArea bufferArea;
    private JTextField produceField, consumeField;
    private JButton produceButton, consumeButton;

        setTitle("生产者消费者模型");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 300);

        bufferArea = new JTextArea(10, 20);
        bufferPanel = new JPanel();

        add(bufferPanel, BorderLayout.CENTER);

        produceField = new JTextField(10);
        consumeField = new JTextField(10);
        produceButton = new JButton("生产");
        consumeButton = new JButton("消费");
        controlPanel = new JPanel();
        controlPanel.add(new JLabel("生产数量："));
        controlPanel.add(produceField);
        controlPanel.add(produceButton);

                        buffer[in] = 1;
                        in = (in + 1) % bufferSize;
                        count++;
                    }
                }

                }
                updateBuffer();
            }
        });

        setVisible(true);

        // 创建生产者和消费者进程
        Thread producerThread = new Thread(new Producer(), "Producer");
        Thread consumerThread = new Thread(new Consumer(), "Consumer");
        producerThread.start();
        consumerThread.start();
    }

    public void updateBuffer() {
        bufferArea.setText("");
        for (int i = 0; i < bufferSize; i++) {
            bufferArea.append(buffer[i] + " ");
        }
    }

    class Producer implements Runnable {
        public void run() {
            while (true) {
                if (count < bufferSize) {
                    buffer[in] = 1;
                    in = (in + 1) % bufferSize;
                    count++;
                    updateBuffer();
                }
                try {
                    Thread.sleep(timeSlice);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }

    class Consumer implements Runnable {
        public void run() {
            while (true) {

                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }

    public static void main(String[] args) {
        new ProducerConsumer();
    }
}

该程序实现了一个简单的生产者消费者模型，其中使用了时间片轮转算法来模拟进程的调度。在程序运行时，会创建两个线程分别代表生产者和消费者进程。生产者进程会不断地向共享缓冲区中添加数据，而消费者进程则会不断地从缓冲区中取出数据。每个进程的时间片为1秒，因此程序会以一定的速率不断地交替执行生产者和消费者进程，模拟了进程调度的过程。

要运行该程序，只需在命令行中输入以下命令：

javac ProducerConsumer.java
java ProducerConsumer
