For example, if 201 was input, the output would be: Flight #201 AUS Austin Scheduled at: 0710 (note that there should be two spaces between 'Austin' and 'Scheduled'). The method version that accepts an integer looks up the airport code, name, and time of flight; the version that accepts a string description looks up the flight number, airport name, and time. The methods return a message if the flight is not found. For example, if 100 was input, the output should be Flight #100 was not found. If no flights were scheduled for the airport code entered, for example MCO, the message displayed should be Flight to MCO was not found. I am having these errors 1-...
