Question

在“请重新启动并再试一次”后，我试图让程序循环开始“你好，你叫什么名字？”

import java.util.Scanner;


public class Learning {

public static void main(String[] args) 

{
    System.out.println("Hello, What is your name?");
    Scanner scanner = new Scanner(System.in);
    String yourName = scanner.nextLine();
    System.out.println("Is: " +yourName + " your name?");

    Scanner scanner1 = new Scanner(System.in);
    String isCorrect = scanner1.nextLine();

    if (isCorrect.equals("Yes"))
    {
        System.out.println("Thank you, Please proceed with the quiz!");
    }
    else
    {
        System.out.println("Please restart and try again.");
        System.exit(0);
    }

Answer 1

只需使用do-while循环并删除System.exit（0）;

do { 

    System.out.println("Hello, What is your name?");
    Scanner scanner = new Scanner(System.in);
    String yourName = scanner.nextLine();
    System.out.println("Is: " +yourName + " your name?");

    Scanner scanner1 = new Scanner(System.in);
    String isCorrect = scanner1.nextLine();

    if (isCorrect.equals("Yes"))
    {
        System.out.println("Thank you, Please proceed with the quiz!");
    }
    else
    {
        System.out.println("Please restart and try again.");
    }
} while (!isCorrect.equals("Yes"));

Answer 2

我添加了一段时间声明：

while(isCorrect.equals("noValue")&&(!isCorrect.equals("yes")||!isCorrect.equals("yes"))) {

所以它一直持续到isCorrect不等于“noValue”并且它等于“是”或“是” 这是整个代码：

import java.util.Scanner;

public class Learning {

public static void main(String[] args) {

String isCorrect = "noValue";
//If isCorrect equals noValue, keep going until it equals yes or Yes
while(isCorrect.equals("noValue")&&(!isCorrect.equals("yes")||!isCorrect.equals("Yes"))) {
    System.out.println("Hello, What is your name?");
    //You don't really need two scanners if they are both for the same thing
    Scanner scanner = new Scanner(System.in);
    String yourName = scanner.nextLine();
    System.out.println("Is: " +yourName + " your name?");

    isCorrect = scanner.nextLine();
    //include the if and else statements so the program knows what to say
    //and if it should repeat or not
    if(isCorrect.equals("yes")||isCorrect.equals("Yes")) {
        System.out.println("Thank you, please proceed with the quiz!");
    } else {
        System.out.println("Please try again");
        isCorrect = "noValue";
    }
}
//Continue with the quiz here!
}
}

我希望我帮忙！

如何让我的脚本循环？
