57,712 PointsOK. This is in a class declaration. What are you trying to create here? I'll make some assumptions:
An instance of GoKart is driving round a track and it drives over an energy Bar. You then want to increment hEadcOunt unless it has already hit the constant MAX_ENERGY_BARS which is set at eigut for all instances of GoKart.
The while statement is in the wrong place - it needs an event to trigger the Test. It is also recursive (to a point) as it will just repeat until the upper bound is reached. That's probably not what you want to achieve, though.
How about a new method, haveCollectedBar... something like:
Private void haveCollectedBar {
If(!isFullyCharged){
mBarsCount++
} else {
// a toast to report a full tank?
}
}
I hope that makes sense.
