用户输入问题

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。 我尝试过使用扫描仪，但由于我对java的缺乏经验而没有缝合工作。 我只是想要求用户输入四名队员的队名和姓名。我通过将这些变量公开，但我不知道如何向他们输入数据，因为他们在单独的类中。

这里是代码

主类 进口java.util.Scanner的; 公共类主要{

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); 


} 

    }

public class Team { 

public String Team_name;

public Team(String Team_name, String name1, String name2, String name3, String name4, Competition comp1, Competition comp2){ 

    this.Team_name = Team_name; 
    this.name1 = name1; 
    this.name2 = name2;

Answer 1

Scanner scanner = new Scanner(System.in); 

System.out.print("Team name: "); 
String teamName = scanner.nextLine(); 
System.out.print("Player 1: "); 
String player1 = scanner.nextLine(); 
System.out.print("Player 2: "); 
String player2 = scanner.nextLine(); 
System.out.print("Player 3: "); 
String player3 = scanner.nextLine(); 
System.out.print("Player 4: "); 
String player4 = scanner.nextLine(); 

Team team = new Team(teamName, player1, player2, player3, player4, comp1, comp2);
