As you can see, we have arrived at the end of this sequel article. By now you should know how to work with multiple threads, create them, make them share data and variables between each other, synchronize attributes, manage their states, and make them communicate between each other. 

Before we finish, there are two more interesting types of classes regarding threads that we should mention. These are the Timer Class and the TimerTask Class. With the help of these we can schedule some parts of our program. Basically, the scheduled task will be run as a separate thread (like a background thread) when its appropriate time arrives. As a rule of thumb, these timer tasks should be quick, otherwise they might hog and/or speed up (since the task was delayed) the application execution. 

Here’s a really quick example; please complete the snippet with the required parts.

class Scheduler{

Timer timer;

public Scheduler(int seconds){

timer = new Timer();

timer.schedule(new RemindTask(), seconds*1000);

}

class RemindTask extends TimerTask{

public void run(){

System.out.println(" Boo! "); // this is the actual task

timer.cancel();

}

}
