在java中，一个接一个地在三个线程内发送数据。

public class SequentialThreadExecution {
    private static final Object lock = new Object();
    private static int currentThread = 1;

    public static void main(String[] args) {
        Thread thread1 = new Thread(new Sender("Thread 1"), "Thread-1");
        Thread thread2 = new Thread(new Sender("Thread 2"), "Thread-2");
        Thread thread3 = new Thread(new Sender("Thread 3"), "Thread-3");

        thread1.start();
        thread2.start();
        thread3.start();
    }

    static class Sender implements Runnable {
        private final String name;

        public Sender(String name) {
            this.name = name;
        }

        @Override
        public void run() {
            synchronized (lock) {
                while (Integer.parseInt(Thread.currentThread().getName().split("-")[1]) != currentThread) {
                    try {
                        lock.wait();
                    } catch (InterruptedException e) {
                        Thread.currentThread().interrupt();
                        System.out.println("Thread interrupted");
                    }
                }
                System.out.println(name + " is sending data.");
                currentThread++;
                lock.notifyAll();
            }
        }
    }
}
