如何解决错误 预期？

Question

代码返回错误<identifier> expected。我不知道为什么会发生此错误。

package com.company;


import java.util.Scanner;


public class Main {

    public static void main(String[] args) {
        intro();
        time();
    }

    public static void intro() {

        System.out.println("Welcome");
        System.out.println("What is your name");
        Scanner input = new Scanner(System.in);

        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 = new Scanner(System.in);

        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?");

        Double money = input.nextDouble();
        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?");

        Double ex = input.double();
        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);
    }
}
