如何实例化游戏(How to Instantiate Game)

 我几乎在Java的每个游戏示例中都看到了这段代码。 创建Game类的实例，然后从该实例执行循环。 
 
public static void main(String[] args) {
    Game g = new Game();
    g.gameLoop();
}

public Game () {
}
 
 但是，因为除了执行gameLoop()之外我什么都不做，为什么不这样写呢？ 我真的不需要在任何地方存储Game实例吗？ 喜欢这个。 
 
public static void main(String[] args) {
    new Game ();
}

public Game () {
    gameLoop();
}
 
 如果是这样的话？ 
 
 这两种情况都在起作用，并且已经过我的测试。 

I see this piece of code in almost every game example for Java. Create an instance of the Game class then execute the loop from that instance.
 
public static void main(String[] args) {
    Game g = new Game();
    g.gameLoop();
}

public Game () {
}
 
However, as I don't do anything apart from the execution of the gameLoop() why not write it like this? I don't really need to store the instance of Game anywhere do I? Like this.
 
public static void main(String[] args) {
    new Game ();
}

public Game () {
    gameLoop();
}
 
If so for what?
 
Both cases are working and have been tested by me.
