Java airline reservation program

I need a program that fits the following scenario: Write an application to assign seats on each flight of the airline’s only plane (capacity: 20 seats). The application should display the following alternatives: Please type 1 for First Class Please type 2 for Economy. If the user types 1, the application should assign a seat in the first-class section (seats 1–6). If the user types 2, the application should assign a seat in the economy section (seats 7–20). The application should then display a boarding pass indicating the person’s seat number and whether it is in the first-class or economy section of the plane. Use a one-dimensional array of primitive type boolean to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the seats are empty. As each seat is assigned, set the corresponding elements of the array to true to indicate that the seat is no longer available. The application should never assign a seat that has already been assigned. When the economy section is full, your application should ask the person if it is acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message "Next flight leaves in 3 hours." Use dialog boxes for input/output. Use an array of booleans to represent the seats on the airplane. Use ints to keep track of the next available seat for each of the seat types.
