java - 无法调用方法？

Question

我有一个 Game 类和一个 TestGame 类，我正在尝试从 Game 调用一个方法到 TestGame。

TestGame.java

public class TestGame {

    Players ceri = new Players("Ceri", 1);
    Players harry = new Players("Harry", 1);
    Players lewis = new Players("Lewis", 1);
    Players kwok = new Players("Kwok", 1);
    Players james = new Players("James", 1);
    Players matthew = new Players("Matthew", 1);


    Game league = new Game("League Table");

    league.addplayer(ceri);

    public static void main(String[] args) {

    }
}

和Game.java

public class Game {

    private String name;

    public Game(String name){
        this.name = name;
    }

    public void addPlayer(Players obj){

    }
}

出于某种原因，我在 league.addPlayer 下面看到了红线。

Answer 1

league.addplayer(ceri); 是代码，而不是初始化程序。

您需要将其放入方法或初始化 block 内。

在本例中，将其放入您的 main 方法中。
