如何创建在不同线程上运行的带有回调的处理程序？

public interface TaskCallback {
    void onTaskCompleted(String result);
}

public class Task implements Runnable {
    private final TaskCallback callback;

    public Task(TaskCallback callback) {
        this.callback = callback;
    }

    @Override
    public void run() {
        // 模拟任务执行
        try {
            Thread.sleep(2000); // 假设任务需要2秒完成
        } catch (InterruptedException e) {
            Thread.currentThread().interrupt();
        }
        String result = "任务完成";
        callback.onTaskCompleted(result); // 任务完成后调用回调
    }
}

public class Main {
    public static void main(String[] args) {
        TaskCallback callback = new TaskCallback() {
            @Override
            public void onTaskCompleted(String result) {
                System.out.println("回调收到: " + result);
            }
        };

        Task task = new Task(callback);
        Thread thread = new Thread(task);
        thread.start();
    }
}
