2,600 PointsI'm trying to decrement the the batteryCount by 1, after 1 lap is completed
Keep getting an error: Task 1 is not passing. I'm sure it's something simple, Help :o(
class GoKart {
public static final int MAX_BARS = 8;
private String color;
private int barCount;
private int lapsDriven;
public GoKart(String color) {
this.color = color;
}
public String getColor() {
return color;
}
public void charge() {
barCount = MAX_BARS;
}
public boolean isBatteryEmpty() {
return barCount == 0;
}
public boolean isFullyCharged() {
return MAX_BARS == barCount;
}
public void drive () {
lapsDriven ++;
if (lapsDriven = 1(){
barCount --;
}
}
}

3,045 PointsIf lapsDriven == 1 in order to decrement the battery, then what happens if 2 laps need to be driven and lapsDriven becomes == 2? The simplest way to handle that is by incrementing lapsDriven by 1 and decrement batteryCount by 1 each time the method is is called.
public void drive (){
lapsDriven++;
barCount--;
}
Sometimes its hard to see the simplest approach, especially when your brain is filled with new information. Happens to me all the time.

559 PointsThe problem is in this line at the end :
if (lapsDriven = 1(){
change it to : if (lapsDriven == 1){
But actually you need to put that in a "for loop" to decrement one barCount after each lapsDriven

3,045 PointsYou over complicated it just a bit. public void drive(){ lapsDriven++; barCount--;} is really all you need here.

Thank you for your response. Of course, makes sense. I tried changing it to == but got the same error.
