Question

in java

1. Write a class called Flight that represents an airline flight. (50 pts)
   1. It should contain instance data that represents the airline name, flight number, departure city, destination cities, and flight price.
   2.   Define the Flight constructor to accept and initialize all instance data.
   3.   Overload the Flight constructor such that the initial value of instance data airline name by Delta.
   4.   Include getter and setter methods for all instance data.
   5.   Include a toString method that returns a one-line description of the flight.
2. Create a driver class called FlightDemo with main method. (10 pts)
   1. Driver class instantiates at least three flight objects and output these airline information.
   2.   Driver class create one flight object to read, update and output one delta flight information.

For 2.1 example:

Set information about three airlines:

"US Air", "Boston", "Los Angeles", 347, 345.67

"Delta", "Philadelphia", "London", 212, 1200.00

"Continental", "Atlanta", "Chicago", 822, 225.25

Output information:

US Air 347 –- From: Boston To: Los Angeles -- price: $345.67

Delta 212 –- From: Philadelphia To: London –- price: $1200.00

Continental 822 –- From: Atlanta To: Chicago –- price: $225.25

Answer 1
