CAR Program

my current prgram displays

current fuel: 15 Gallon(s) current mileage : 0

prompt user how many miles do you want to drive? user enters any amount then car drives Fuel Gauge displays amount of fuel left and the Odometer number of miles driven. When the car reaches number of miles that user wants to drive. The program displays you have reached your destination with certain amount of left. If the car runs out of fuel at any time during the disired amount of miles to drive, prompt user to enter amount of fuel in gallons. Max amount of gallons that the tank can hold is 15 gallons. 1 gallon drives 24 miles. if the Odometer reaches 999,999 miles it will reset to 0.

The car will also diplay fuel used and cureent mileage after driving

1 gallon of fuel drives 24 miles therefore with 15 gallons of fuel the car will drive 360 miles

Scenarios i have tested

if the car drives 24 miles the odometer shows 24 miles and current fuel 14 gal ( this is not working) if the car drives 240 miles the odometer shhows 240 miles and current fuel 5 Gallons (this is working)

if the car drives 360 miles the odometer shhows 360 miles and current fuel 0 Gallons (this is not working) if the the distance in miles is over 999999 the the odometer resets to 0 and continues counting miles ( this is not working)

I have a problem with my code but i cannot find it. Certain scenarios work and others do not. Also some of my calculations are off.

HERE IS MY CODE

//Fuel Gauge Class

public class FuelGauge { // instance variable private int fuel;

// know about current fuel public void setFuel(int fuel) { this.fuel = fuel; }

// report current fuel public int getFuel() { return fuel; }

// increae current fuel public void increaseFuel() { if (fuel <= 15) fuel++; }

// decrease current fuel public void decreaseFuel() { if (fuel > 0) fuel--; }

}
