Hi all,
It's probably really silly what I'm missing here, but I'm uncertain as to how to call in the new drive method AND how to ''pass it a 1 as a default''
Thanks!
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;
lapsDriven -= barCount;
}
public void drive() {
return lapsDriven += 1;
}
}

PHP Development Techdegree Graduate 48,637 PointsIt's very simple; you just call the drive()
method, passing 1
as its argument.
public void drive() {
drive(1);
}
