请问，为什么我字段必须要加static静态字段啊，我后面 new对象使用 get ，set应该不用加静态字段啊。谢谢！！
不是必须的吧，得看你的需求
该回答通过自己思路及baidu搜索,得到内容具体如下：
在Java中，静态字段是属于类的，而非属于类的实例对象。这意味着，在没有创建类的实例对象时，静态字段就已经存在，可以直接使用。
对于非静态字段，需要先创建类的实例对象，然后通过该实例对象才能访问和使用它们。
因此，如果你想在没有创建类的实例对象时就能够访问和使用字段，就需要将字段定义为静态的。
在你的代码中，如果你想在类的构造方法中使用非静态字段，需要先创建类的实例对象，然后通过该实例对象才能访问和使用它们。例如，可以在构造方法中使用以下代码来设置非静态字段的值：
public DartGame() {
this.dartsNumber = 0;
this.player = new Player();
}
在使用类的实例对象调用get和set方法时，也不需要使用静态字段。例如，可以使用以下代码来设置playerScore的值：
DartGame game = new DartGame();
game.setPlayerScore(10);
注意，静态字段与非静态字段的作用域和生命周期不同，需要根据具体的需求和设计来选择使用哪种类型的字段。
如果以上回答对您有所帮助，点击一下采纳该答案～谢谢
get set 写在哪里 代码贴全
你哪句代码出错就贴哪句代码，不要贴不出错的代码出来
最好是把代码贴全
不要玩你猜我猜的游戏
