Here is my question: I would like to display the new schedule showing the delayed arrival, departure, and day at the delayed station. How would I do that?

10. [40 marks] A train timetable for a train travelling between Vancouver and Toronto is given below Station Vancouver Kamloops Jasper Edmonton Saskatoon Winnipeg Sioux Lookout 05:0205:42 Hornepayne 15:35 16:10 Capreol Toronto ArrivaDeparture Da 20:30 1 06:00 06:35 16:0017:30 23:00 23:59 08:00 08:25 20:45 22:30 4 4 00:18 00:48 09:30 Store the information from each row of the table in an object. Then, arrange the objects in an ArrayList structure Your program should now take the following commands in a continuous loop I. Show-shows the full table II. Delay -the arrival of the train is delayed by at station ; that is, add the delay to the corresponding station entry. For example, Delay Edmonton 30 implies that the train would arrive 30 minutes later than the expected time of arrival in Edmonton. The new entry would be "Edmonton 23:30 00:29 3". All stations following Edmonton will also update their arrival and departure by +30 minutes, and consequently the day of arrival and departure as well. The result of this Delay command is shown below
