what means with handling the new parameter??
class GoKart {
public static final int MAX_BARS = 8;
private String color;
private int barCount;
private int lapsDriven;
private int laps;
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(int laps) {
// todo something to handle the new parameter laps..
lapsDriven++;
barCount--;
}
}

Please examine this:
public void drive(int laps) {
// todo something to handle the new parameter laps..
lapsDriven++;
barCount--;
}
if you pass in laps = 7
then
what you should be doing (hard coded)
lapsDrives += 7 barCounts -= 7
So, for your case, it would be (pseudo code)
lapsDriven += laps;
barCount -= laps
If this answers your question, please mark the question as answered.

the lapsDriven+= 2 ; --->this is adding 2 laps barCount-= 2 ; ----> this takes 2 bars away from battery
remember each lap takes away 1 energy bar and we drove 2 laps around track the only part that confused me was deciding on the parameter private int laps. i didnt know i had to do this, until i remembered that we couldnt use lapsDriven

public void drive(int laps) { lapsDriven+= 2 ; barCount-= 2 ; }

2,961 Pointshey Bryan, How come your method come true over here, Why do you want to decrease barCount by 2 and increase every lapsDriven by 2, Would you please explain

27,299 PointsIf you got the challenge wrong - notice the comment (make use of += and -=). You want to increase the lapsDriven variable by laps. In other words you want to use the increment operator += to increase that variable. The same goes for barCount except you want to decrement (-=).
