Thread: Balloon code

the blue should produce that the first balloon's alt is 250 - 100, 150. instead it gives 400, and the next should say its alt is at the same, instead it stays at its own.

It gave me wrong outputs.

its on a different file in my src folder.

--- Update ---

When I replace the adjustAltitude methods in

myBalloon.adjustAltitude(myBalloon.getAltitude() - 100);

and

myBalloon.adjustAltitude(myBalloon.getAltitude() * 3)

with descendTo and ascendTo it gives me correct results. Any idea why that makes a difference?

I posted the class definition. The adjustAltitude method adjusts the altitude to w.e. i put it as long as its > 0. When I call it in the statement

myBalloon.adjustAltitude(myBalloon.getAltitude() - 100);

it should produce the output that myBalloon 'Spider-Man' has an alt of 150 (250-100), instead it gives me 400. But when i replace that method with the method descendTo, it gives me the correct output. Same thing happens with the line

myBalloon.adjustAltitude(myBalloon.getAltitude() * 3)

From my reading adjustAltitude *adds* the parameter to the current altitude.

It just replaces the altitude to w.e is in the argument. The current altitude at the time of that first statement is 250, and when i subtract 100 it gives me 400 in the output.

The problem is solved. using

myBalloon.adjustAltitude(myBalloon.getAltitude() - 100);

would mean add the altitude to itself (doubling it) then subtracting 100. by jusing

myBalloon.adjustAltitude( - 100);

it subtracts 100 from the current altitude. Thanks everybody for all your help.
