java - 从循环中获取数组元素

Question

我试图从数组中获取一个元素并稍后在我的代码中使用它，但我的代码中有一些逻辑错误。我希望用户输入他或她需要清洁的日期，然后打印出清洁的日期。这是代码:

import java.util.Scanner;

public class arrayLoopTest {

    public static void main(String[] args) {
        Scanner scr = new Scanner(System.in);
        String[] days = { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday" };

        int i = 0;
        while (true) {
            System.out.println("On what day should the cleaning be scheduled ? ");
            String schedule = scr.nextLine();

            for (i = 0; i < days.length; i++) {

                if (days[i].equals(schedule)) {

                    System.out.println("Cleaning scheduled for " + schedule);

                } else {
                    System.out.println("Invalid, You have to choose one of these days: \n " + days[i]);
                }
            }

        }
    }
}

控制台输出

On what day should the cleaning be scheduled ? 
Thursday
Invalid, You have to choose one of these days: 
Monday
Invalid, You have to choose one of these days: 
Tuesday
Invalid, You have to choose one of these days: 
Wednesday
Cleaning scheduled for Thursday
Invalid, You have to choose one of these days: 
Friday
Invalid, You have to choose one of these days: 
Saturday
Invalid, You have to choose one of these days: 
Sunday
On what day should the cleaning be scheduled ? 

Answer 1

一个非常简单的方法是添加另一个变量:

String savedVar = ""; 
....
if (days[i].equals(schedule)) {
            savedVar = schedule; //save your user input here
            System.out.println("Cleaning scheduled for " + schedule);

        } else {
            System.out.println("Invalid, You have to choose one of these days: \n " + days[i]);
        }

然后稍后在代码中使用savedVar。
