Java Timer: Scheduling a Task Once with schedule(TimerTask task, long delay) | Timer and TimerTask

In this Java tutorial, we explore how to schedule a task to run once using the `schedule(TimerTask task, long delay)` method of the `Timer` class.

The `Timer` class in Java allows you to schedule tasks to be executed at specific times or after a certain delay. The `schedule(TimerTask task, long delay)` method is particularly useful when you want to schedule a task to run once after a specified delay.

Here's how it works:

1. **Create a Timer object**: First, create an instance of the `Timer` class.

2. **Create a TimerTask object**: Next, create a subclass of the `TimerTask` class and override the `run()` method with the code you want to execute.

3. **Schedule the task**: Use the `schedule()` method of the `Timer` object to schedule the task. Pass the `TimerTask` object and the delay in milliseconds as arguments to this method.

```java
Timer timer = new Timer();
TimerTask task = new TimerTask() {
@Override
public void run() {
// Your task code goes here
}
};
long delay = 5000; // Delay in milliseconds (e.g., 5000 milliseconds = 5 seconds)
```

4. **Task execution**: After the specified delay, the `run()` method of the `TimerTask` object will be executed.

5. **Cleanup**: It's good practice to cancel the timer when it's no longer needed to release associated resources.

```java
```

By following these steps, you can schedule a task to run once after a specified delay using the `schedule(TimerTask task, long delay)` method of the `Timer` class.
