如何在Java中单独读取行

Question

我正在使用Java进行Nim游戏，如果游戏中有两个人类玩家，我的部分代码是读两个名字，但是当我运行代码时，它打印出要求名字和要求第二个名字的声明，只允许我输入第二个玩家的名字。有人能帮忙吗？谢谢！

System.out.println("Please enter a name for Player 1: ");
String player1Name = scan.nextLine();
player1.setName(player1Name);
System.out.println("Please enter a name for Player 2: ");
String player2Name = scan.nextLine();
player2.setName(player2Name);

Answer 1

试试这个：

String player1Name = scan.next();

Answer 2

试试这个：

public class sendMessageToServerCommand implements Command {

    @Override
    public void execute(String msg){
          sendToServerTheMsg(msg);
    }
}

..
Command command=new sendMessageToServerCommand();
command.execute("msg I got on runtime");
