变量不在范围内（我认为），但不确定如何解决它

Question

我正在做的只是练习测试，我认为它做得很好，但我得到了，我认为是一个范围问题。它说，“团队无法解决变量类型”，我尝试了一些我认为会修复它的东西，但它们没有用。这是代码：

import java.util.Scanner; public class fundamentalsofgame {

public String hteam;
public String cteam;

public String teams(String hometeam, String compteam){
    String hteam = hometeam;
    String cteam = compteam;


    return "The teams are " + hteam + " vs " + cteam;

}

public static void main(String[] args){

    Scanner scanner = new Scanner(System.in);
    String hometeam;
    String awayteam = "New England Cheatriots";

    hometeam = scanner.next();

    teams team = new teams(hometeam, awayteam); //error

}

}

Answer 1

teams是一种方法，而不是您的类名，而是fundamentalsofgame。因此，您需要创建fundamentalsofgame的对象并在其上调用teams方法。改变这个：

teams team = new teams(hometeam, awayteam); //error

到

fundamentalsofgame obj = new fundamentalsofgame();
fundamentalsofgame.teams(hometeam, awayteam);
