528 PointsProtect the call to kart.drive by handling the IllegalArgumentException that is thrown when not enough battery remains.
I can't find what is wrong with my code!
class Example {
public static void main(String[] args) {
GoKart kart = new GoKart("purple");
if (kart.isBatteryEmpty()) {
System.out.println("The battery is empty");
}
}
try {
kart.drive(42);
System.out.println("There is enough battery to use.");
} catch (IllegalArgumentException iae) {
System.out.println("Not enough battery remains.");
}
}
class GoKart {
public static final int MAX_BARS = 8;
private int barCount;
private String color;
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);
}
public void drive(int laps) {
if (laps > barCount) {
throw new IllegalArgumentException("Not enough battery remains");
}
lapsDriven += laps;
barCount -= laps;
}
}

5,604 PointsHi there! Just a simple issue with the placement of your curly braces }
class Example {
public static void main(String[] args) {
GoKart kart = new GoKart("purple");
if (kart.isBatteryEmpty()) {
System.out.println("The battery is empty");
}
// <--- There was a closing curly brace placed here
try {
kart.drive(42);
System.out.println("There is enough battery to use.");
} catch (IllegalArgumentException iae) {
System.out.println("Not enough battery remains.");
}
}
} //<--- That needed to be here
Take care! and happy coding :)
