confused
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++;
barCount--;
public void drive() {
lapsDriven++;
barCount--;
}
public void drive(int numberOfLaps) {
while (numberOfLaps > 0) {
drive();
numberOfLaps--;
}
}

You want to modify the existing drive method to accept an argument- so add a parameter. Then you need to use that parameter to update lapsDriven and barCount, adding the value passed in to lapsDriven, and subtracting the value from barCount. I hope this helps.
public void drive(int laps) {
lapsDriven += laps;
barCount -= laps;
}

public void drive() { lapsDriven++; barCount--; public void drive() { lapsDriven++; barCount--; }
public void drive(int numberOfLaps) { while (numberOfLaps > 0) { drive(); numberOfLaps--; }
what the problem is asking for is for you to just modify actual method to accept an int paramater:
public void drive(int laps) {
}
next inside that method
you add the actual laps driven by parameter like so:
lapsDriven = lapsDriven + laps;
and do the same for barCount:
barCount = barCount + laps;
if you still have questions please let us know.
final code should look like this:
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(int laps) { lapsDriven+= laps; barCount-= laps; } }
