here:
public double reFuel()
//refueling each ship returns it to its full fuel capacity
{
fuelCurrent = fuelCapacity;
}
and here:
//prints out the fuel consumed for each ship in the fleet
public double printSummary()
//prints out fuelConsumed for each ship
{
System.out.println(ship1.getName() +" 's total fuel consumption is " + ship1.getFuelConsumed());
System.out.println(ship2.getName() +" 's total fuel consumption is " + ship2.getFuelConsumed());
System.out.println(ship3.getName() +" 's total fuel consumption is " + ship3.getFuelConsumed());
System.out.println(ship3.getName() +" 's total fuel consumption is " + ship4.getFuelConsumed());
}
You have two methods, you have said that they will return double
but in their body there is no return A_DOUBE
. fix them with adding return statement
or just make them void
depends on your problem.
