Question

Seoul Garden Sdn Bhd serves a wide range of seafood selections such as tasty crabs, fresh prawns, chicken fillets & many more for steamboat and grill. This buffet restaurant serves up 150+ choices of fresh seafood, fruits, and cold & hot beverages.

The price of the steamboat per person is shown in Table 1:

Age (years) Price (RM)

________________________

6 - 12 RM 11

> 13 RM 25

________________________

*I can't draw a table so I do like this :'(

Seoul Garden Sdn Bhd also gives an appreciation for the member cardholder with 6% off from the total price. The above price excludes government tax of RM 5.60.

Write an application that accepts the customer’s age and member status (member or non-member) by using a JOptionPane procedure and prints out the total price.

Answer 1

import javax.swing.*;

public class Restaurant {

    public double cost1 = 11; // For children from 6 to 12 years old
    public double cost2 = 25; // For children aged 13 and over
    public double bond = 5.60;
    public double cost = 0;


    public void Calculation(int age, String participant) {

        if(age < 6){
            JOptionPane.showMessageDialog(null, "Age input error","Error",JOptionPane.ERROR_MESSAGE);
        } else if (age <= 12 & age >= 7) {
            cost += cost1;
            if (participant.equals("yes")) {
                cost -= cost * 0.06;
            }
            cost += bond;
            JOptionPane.showMessageDialog(null, cost, "Information", JOptionPane.INFORMATION_MESSAGE);
        } else {
            cost += cost2;
            if (participant.equals("yes")) {
                cost -= cost * 0.06;
            }
            cost += bond;
            JOptionPane.showMessageDialog(null, cost, "Information", JOptionPane.INFORMATION_MESSAGE);

        }
    }

    public static void main(String[] args) {
        Restaurant rez = new Restaurant();

        String age1 = JOptionPane.showInputDialog("Enter customer age");
        int age = Integer.parseInt (age1);
        String participant = JOptionPane.showInputDialog("Whether the client is a member of the restaurant yes/no");

        rez.Calculation(age, participant);
    }
}
