从另一个方法抓取字符串

Question

我正试图将字符串“otheruser”从静态void Answer2返回到main方法。

public static void main(String[] args) {
    System.out.println("is there another person with you?");

    Scanner Answer2 = new Scanner(System.in);
    String answer2 = Answer2.nextLine();
    if (answer2.equals("yes")) {
        System.out.println("ok then type there name in please");
        Answer2();
    } else if (answer2.equals("no")) {
        System.out.println("ok then good day");
    }

    System.out.println("how old are you " + Answer2());
}

static void Answer2() {
    Scanner otheruser = new Scanner(System.in);
    String Otheruser = otheruser.nextLine();
    System.out.println("hi " + Otheruser);
}

Answer 1

您可以返回从扫描器获得的字符串，而不是打印从扫描器获得的字符串，这样程序的其余部分就可以使用它：

static String answer2() { 
    Scanner otheruser = new Scanner(System.in);
    String otherUser = otheruser.nextLine(); 
    return otherUser;
}
