In this lab, you complete a partially written Java program for an airline that offers a 25 percent discount to passengers who are 6 years old or younger and the same discount to passengers who are 65 years old or older. The program should request a passengers name and age, and then print whether the passenger is eligible or not eligible for a discount. 1. Open the file named Airline. java using Notepad or the text editor of your choice. 2. Variables have been declared and initialized for you, and the input statements have been written. Read them carefully before you proceed to the next step. 3. Design the logic deciding whether to use AND or OR logic. Write the decision statement to identify when a discount should be offered and when a discount should not be offered. 4. Be sure to include output statements telling whether or not the customer is eligible for a discount. 5. Compile the program. 6. Execute the program, entering the following as input a. Customer Name: Wil Moriarty Customer Age 11 What is the output? b. Customer Name: James Chung Customer Age 64 What is the output? c. Customer Name: Darlene Sanchez Customer Age 75 What is the output? d. Customer Name: Ray Sanchez Customer Age 60 What is the output? e. Customer Name Tommy Sanchez Customer Age: 6 What is the output? f Customer Name: Amy Patel Customer Age:8 What is the output?

Explanation / Answer

PROGRAM CODE:

package util;

import javax.swing.*;

public class Airline

{

public static void main(String args[])

{

String passengerName = ""; // Passenger's name.

String ageString = ""; // String version of passenger's age.

int passengerAge = 0; // Passenger's age.

// This is the work done in the housekeeping() method

passengerName = JOptionPane.showInputDialog("Enter passenger's name: ");

ageString = JOptionPane.showInputDialog("Enter passenger's age: ");

  

passengerAge = Integer.parseInt(ageString);

  

if(passengerAge<=6 && passengerAge >=65 && passengerAge > 0)

      System.out.println("Eligible for 25% discount");

else System.out.println("Not eligible for 25% discount");

// This is the work done in the detailLoop() method

// Test to see if this customer is eligible for a 25% discount.

  

  

// This is the work done in the endOfJob() method

System.exit(0);

}

}
