Question

我需要一种方法来允许用户输入团队名称和团队成员名称。我尝试使用扫描仪，但由于我对java的经验不足，因此无法工作。我只是想让用户输入四个团队成员的团队名称和名称。我把这些变量公之于众，但我不知道如何将数据输入它们，因为它们属于单独的类。

这是代码

主要课程 import java.util.Scanner; 公共课主要{

public static void main(String[] args) {
    Competition comp1 = new Competition("First competition", "IUS team1", "IUS team2" ,2014 );
    Competition comp2 = new Competition("Second competition" , "IUS team3", "IUS team4", 2016);
    Scanner jin = new Scanner(System.in);
    Team teamObject1 = new Team(String Team_name);
    String Team_name = teamObject1.jin.nextLine();

    //Team team1 = new Team("IUS team1", "Adin", "Merzuk", "Segmedina", "Iman", comp1, comp2); 
    Team team2 = new Team(team1); 


    System.out.println(team1);


}

   }
