* The function that is running, no exit can not take effect, such as the new `System.out.println` added below, only the `run()` function will take effect.
```java
public class MathGame {
public static void main(String[] args) throws InterruptedException {
MathGame game = new MathGame();
while (true) {
game.run();
TimeUnit.SECONDS.sleep(1);
// This doesn't work because the code keeps running in while
System.out.println("in loop");
}
}
public void run() throws InterruptedException {
// This works because the run() function ends completely every time
