479 PointsI have no idea what i suppose to do..
i did watch the video but still don't understand what is it about. The question is : In your newly created drive method, increment the new lapsDriven variable by 1. Use the incrementing shorthand to increase lapsDriven.
class GoKart {
public static final int MAX_BARS = 8;
private String color;
private int barCount;
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;
}
private int lapsDriven;
}

24,063 PointsThe shorthand or incrementing and decrementing is pretty consistent across programming languages. it's simply
lapsDriven++; // will increment by 1
lapsDriven--; // will decrement by 1
If you want to add or subtract values, there's a shorthand for that as well
lapsDriven += 5;
lapsDrive -= 5;
