1. Find and remove errors from above above.
2. Improve the quality of code by following programming standards from above.

// 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.

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

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

passengerName = s.nextLine();

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

passengerAge = s.nextInt();

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

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

{

System.out.println("Passenger name: " + passengerName);

System.out.println("Passenger age : " + passengerAge);

System.out.println("This passenger is eligible for a 25% discount.");

}

else

{

System.out.println("Passenger name: " + passengerName);

System.out.println("Passenger age : " + passengerAge);

System.out.println("This passenger is not eligible for a 25% discount.");

}

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

System.exit(0);

}

}

3. Document and implement at least two different test cases following the format given below from above.
