Answer 1

Here you go as requested I have provided the code with

appropriate comments and variable names.

If there is any further query kindly add it as a comment.

Note: here I have used the logical OR represented by || in the if condition

******************************************************************

You can either add these lines after the comment

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

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

******************************************************************

System.out.println("Customer Name: " + passengerName);

System.out.println("Customer Age: " + passengerAge);

// This is the conditional statement which checks if the passengerAge is lesser

// than or equal to 6 or if the passenger's age is greater than or equal to 65.

if ((passengerAge <= 6) || (passengerAge >= 65)) {

System.out.println("Passenger is eligible for a discount");

} else {

System.out.println("Passenger is not eligible for a discount");

}

*****************************************************************

This is the complete code with the above changes

*****************************************************************

//Airline.java - This program determines if an airline passenger is

//eligible for a 25% discount.

import java.util.Scanner;

public class Airline {

public static void main(String args[]) {

Scanner s = new Scanner(System.in);

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

System.out.println("Enter passenger's name: ");

passengerName = s.nextLine();

System.out.println("Enter passenger's age: ");

ageString = s.nextLine();

passengerAge = Integer.parseInt(ageString);

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

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

System.out.println("Customer Name: " + passengerName);

System.out.println("Customer Age: " + passengerAge);

// This is the conditional statement which checks if the passengerAge is lesser

// than or equal to 6 or if the passenger's age is greater than or equal to 65.

if ((passengerAge <= 6) || (passengerAge >= 65)) {

System.out.println("Passenger is eligible for a discount");

} else {

System.out.println("Passenger is not eligible for a discount");

}

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

System.exit(0);

}

}
