How do I solve this step?
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() {
drive(1);
}
try{
public void drive(int laps) {
lapsDriven += laps;
barCount -= laps;
}
}catch(IllegalArgumentException){
System.out.print("There are not enough energy");
}
}

1,986 Pointsi Still can't solve it ?? my code: public void drive(int laps) { lapsDriven += laps; int noBar = barCount -= laps; if(noBar < 0){ throw new IllegalArgumentException("LOW BATTERY"); } }
Error: Make sure you throw the exception before you change the barCount and lapsDriven fields.
