Question

Using the code below how would I create scenes in JAVAFX to play the two-game applications. The user should have the slection to choose to play blackjack game or the snake game. How would I get both of the games below to be in one program and then let the user select which to play and go exit if necessary?

Next game

similar to code above, another game like above that uses JAVA fx and images and such

Explanation / Answer

You can use java.util.TimerTask is an abstract class that implements Runnable interface and we need to extend this class to create our own TimerTask that can be scheduled using java Timer class. Java Timer class is thread safe and multiple threads can share a single Timer object without need for external synchronization. Timer class uses java.util.TaskQueue to add tasks at given regular interval and at any time there can be only one thread running the TimerTask, for example if you are creating a Timer to run every 10 seconds but single thread execution takes 20 seconds, then Timer object will keep adding tasks to the queue and as soon as one thread is finished, it will notify the queue and another thread will start executing.
