java - 如何使用if else语句和对话框？

Question

我有一项学校作业需要我为剧院制作票务系统。所以条件是周一至周四，10岁以下的人免费，10岁至65岁的人要付RM10，65岁以上的人也免费。周五至周日，10岁以下需支付 RM10，10-65 岁需支付 RM20，65 岁以上需支付 RM10。

我尝试放入对话框，到目前为止我得到了这个:

import javax.swing.*;
public class NewTicketSystem {

public static final String [] days = { "Monday", "Tuesday", "Wednesday", "Thursday",
        "Friday", "Saturday", "Sunday"};

public static void main(String[] args) {

    JFrame frame = new JFrame("Input Dialog Example 3");
    String Day = (String) JOptionPane.showInputDialog(frame, 
        "Which day do you want to choose?",
        "Day",
        JOptionPane.QUESTION_MESSAGE, 
        null, 
        days, 
        days[0]);

    System.out.printf("Chosen day is %s.\n", Day);

    JFrame frames = new JFrame("InputDialog Example #1");


    String UserAge = JOptionPane.showInputDialog(frames, "What is your age?");

    System.out.printf("Your age is '%s'.\n", UserAge);

     System.exit(0);


    }

}

我现在的问题是，如何将条件放入编码中？我尝试过在网上搜索但仍然无法理解。请尽可能用简单的语言解释。

提前致谢。

Answer 1

int price;

if (Day.equals("Monday") || Day.equals("Tuesday") || Day.equals("Wednesday") || Day.equals("Thursday")) { //Monday - Thursday
    if (UserAge >= 10 && UserAge <=65) //10-65
        price = 10;
    else //Under 10 and Above 65
        price = 0;
} else { //Friday - Sunday
     if (UserAge >= 10 && UserAge <=65) //10-65
         price = 20;
     else //Under 10 and Above 65
         price = 10;
}
