Question

import java.util.Scanner;

public class Fernando {
    public static void main(String[] args) {
        Scanner skype = new Scanner(System.in);
        System.out.print("What is your name ")?
        String n = skype.nextLine(); // This is the line with the error
        System.out.print("\n and how old are you?");
        int y = skype.nextInt();
        displayInfo(n,y);
    }

    public String displayInfo(String name, int age){
        return name +" is "+ age+" years old.";
    }
}

所有这一切都是预料之中的。我根本不明白什么是错的。

尝试更改

System.out.print("What is your name ")?

为：

System.out.println("What is your name?");

这应该有效，因为你有？而不是;。

字符串预期错误？
