How do I add several objects to an ArrayList in JAVA using a loop?
![Overview:
A new airways company wants to make a simple application to keep track of flights and
passengers.
In this TMA, it is required to help the head of the company implement the required application.
Requirements:
After a quick meeting with the head of the company, you got the following information:
• It is required to store the whole data in one collection
Each flight has a number, a pilot and a specific date. In addition, passengers could be added
or removed within a given limit for the maximum number of passengers who could be in the
same flight. Furthermore, there are other attributes (add at least 3 attributes from your
choice). Of course, flight number is unique within the same date.
• Each pilot has a unique ID, a name and other attributes (add at least 2 attributes from your
choice).
• Each passenger has a unique passport number, a name and other attributes (add at least 2
attributes from your choice but one of them should be common with pilots).
Moreover, you have been informed that the following operations happen frequently:
• Offering a new flight
• Adding a passenger to a specified flight
Removing a passenger from a specified flight
Retrieving the average number of passengers per flight of a specified date
• Displaying all available flights in a format similar to the following:
date1: flightNo1 flightNo2 flightNo3 .
date2: flightNo1 flightNo2 flightNo3 .
where dates and flights are sorted in ascending order
• Saving all the data into a text file](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F274ad608-8212-43be-a4da-26680d5ad513%2F82eed432-4ca5-407c-850b-96e92481f7c2%2Faqm17e_processed.png&w=3840&q=75)
