重定向错误消息的代码流

Question

我想在else语句之后将代码流重定向到“1”部分。我试图通过创建循环和不同的方法来实现它，但我无法做到。我想要的是，当给出无效答案时会出错，并会再次提问。import java.util.Scanner;public class OddsAndEvens {    public static void main(String[] args) {        Scanner input = new Scanner(System.in);        System.out.println("Let’s play a game called “Odds and Evens”");        System.out.println("What is your name?");        String name = input.next();        // 1 <------------------------        System.out.println("Hello " + name + " which one do you choose? (O)dds or (E)vens?");         String oe = input.next();        if (oe.equalsIgnoreCase("e")) {            System.out.println(name + " has picked evens! The computer will be odds.");        }        if (oe.equalsIgnoreCase("o")) {            System.out.println(name + " has picked odds! The computer will be evens.");        }        else {            System.out.println("You have typed an invalid answer.");        }    }}
