In the `App` class, we can see how the `World` class and its methods are used to create a game world, add entities to it, and start the game loop.
```java
var world = new World();
var skeleton1 = new Skeleton(1, 10);
var skeleton2 = new Skeleton(2, 70);
var statue = new Statue(3, 20);
world.addEntity(skeleton1);
world.addEntity(skeleton2);
world.addEntity(statue);
world.run();
Thread.sleep(GAME_RUNNING_TIME);
world.stop();

public class App {
private static final int GAME_RUNNING_TIME = 2000;
public static void main(String[] args) {
try {
var world = new World();
var skeleton1 = new Skeleton(1, 10);
var skeleton2 = new Skeleton(2, 70);
var statue = new Statue(3, 20);
world.addEntity(skeleton1);

Thread.sleep(GAME_RUNNING_TIME);

This is a basic implementation of the Update Method pattern. In a real-world application, the `Entity` class would likely have additional methods and properties, and the `update` method would contain more complex logic to simulate the entity's behavior.
