How to set a timeout for the Java Runnable interface?

In Java, the Runnable interface does not have a direct method for setting a timeout. However, you can use a Thread to set a timeout. Here is one possible way to do so:

1. Create a Runnable object that implements the run method, which contains the code you want to execute.

Runnable runnable = new Runnable() {
    @Override
    public void run() {
        // 执行你的代码
    }
};

1. Create a Thread object and pass the Runnable object as a parameter to the constructor of the Thread.

Thread thread = new Thread(runnable);

1. Set a timeout period and use the join method of the Thread class to wait for the thread to finish execution. If the thread has not completed within the specified time, it will be considered as a timeout.

long timeout = 5000; // 指定超时时间，单位为毫秒

try {
    thread.start(); // 启动线程
    thread.join(timeout); // 等待线程执行完成，最多等待timeout毫秒
} catch (InterruptedException e) {
    e.printStackTrace();
}

if (thread.isAlive()) {
    // 如果线程还活着，说明超时了
    thread.interrupt(); // 中断线程
}

By using the code above, you can set a timeout for executing a Runnable task and interrupt the thread after the timeout. Please note that this method only interrupts the thread and does not guarantee that the code in the Runnable task will also stop executing. Therefore, when writing a Runnable task, make sure to catch InterruptedException to properly handle the thread termination logic when the thread is interrupted.
