Intercort Airways - java

IntercortAirways Tried my best to convert the code from c++ into java A program use to record the total weight that a flight can carry load. Then parcels are loaded into the flight until it full. There are 3 flights. In the end user can generate a report all flights and how much profits gained. I used Netbeans to create and run my code. Below are the print screens.
