JVM没有读取其中的一段代码，有什么问题吗？[副本]

Question

我将这段代码复制并粘贴到我的Intellij中，结果显示系统不允许用户回答（输入）“您目的地的三字母货币符号是什么？”它直接跳到下一个问题。请问问题是什么，解决办法是什么？首先感谢您的教导。

这段代码是我从Java的实践和学习链接中获得的：如何修复预期的错误 ？

package com.Test3;

import java.util.Scanner;

public class Example1 {


    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        intro(input);
        time(input);
    }

    public static void intro(Scanner input) {
        System.out.println("Welcome");
        System.out.println("What is your name");

        String name = input.nextLine();
        System.out.println("Nice to meet you, " + name + " where are you travelling to?");
        String dest = input.nextLine();
        System.out.println("Great! " + dest + " sounds like a great trip");
    }

    public static void time(Scanner input) {
        int hours, minutes;
        float perd, perdc, change;



        System.out.println("How many days are you going to spend travelling?");

        int days = input.nextInt();

        hours = days * 24;
        minutes = hours * 60;

        System.out.println("How much money in USD are you going to spend?");

        float money = input.nextFloat();
        perd = money / days;

        System.out.println("What is the three letter currency symbol of your destination?");

        String curr = input.nextLine();

        System.out.println("How many " + curr + " are there in 1USD?");

        float ex = input.nextFloat();
        change = money * ex;
        perdc = perd * ex;

        System.out.println("If you are travelling for " + days + " that is the same as " + hours + " or " + minutes + " minutes");
        System.out.println("If you are going to spend " + money + " $USD that means per day you can spend upto $" + perd + " USD");
        System.out.println("Your total budget in " + ex + " is " + change + ex + " ,which per day is  " + perdc + curr);
    }

}

不要使用nextline。它做了医生说的，但它不是你想要的，因此，“坏了”。

相反,正确配置扫描仪；完成后，调用:scanner.usedelimiter（“\\r”）；（它告诉扫描器标记由换行符分隔），并使用.next()读取一行文本。
