Add a boolean instance variable that monitors if the engine is on or off. Add a boolean instance variable that monitors if the plane is landed. Create new methods: o public void startEngine ( ) set the boolean variable to the appropriate value and print a message Example: Delta 747 2021 engine started. o public void landAndStopEngine ( ) set the boolean variables to the appropriate value and print a message. Example: Delta 747 2021 was landed and stopped. o public boolean isEngineOn ( ) return true if the engine is on, returns false otherwise. • Modify existing methods with a warning message if the plane is, or is not, running and do not perform the requested action when appropriate. For example, the plane engine must be running to fly. The plane must be landed and turned off to add fuel, or check for inspection. Examples: Delta 747 2021 must be ON to fly. 1. 2. Delta 747 2021 must be landed and OFF to add fuel. More Methods - continuation • private double calcRange () - calculate the total range (maximum hours to fly) based on the fuel in the tank and the gallons per hour of the plane. • private double calcGasNeededToFillTank () - calculate the fuel needed to fill the tank. public void simulateMultiCityTrip (int numberCities ) – Use a loop to simulate a plane flying to a number of cities, entered as input parameter. You must invoke the fly and addGas methods. Inside of the loop you need to do the following: invoke the calcRange () method to figure out the maximum hours you can fly with the fuel that you have in the tank generate an integer random number to simulate the number of hours needed to fly to get to the next city. This random number should be an integer number between 1 and the
